23.1 Legacy Series / Re: Policy based routing w/Mullvad Wireguard - Help needed

« on: April 04, 2023, 10:23:59 pm »

Main thing is create a new local config for wireguard - MUST have routes disabled.
Then an endpoint must be created, and must successfully connect. 0.0.0.0/0 must be pushed across that.
Then a new WG interface must be created (virtual interface must exist) and create a single gateway with higher priority (so default traffic wont use it).


With this you now need very little to complete -
Aliases - the pc's or whatever you want to use the tunnel,
At least 1 firewall rule - that must match traffic before any other rules and have the new WG gateway set.
(eg: source could be your pc's in the alias you want to use the tunnel and destination any).

You dont need outbound nat or any floating rules or static routes if you configure it in this simple way.

Zenarmor (Sensei) / Re: My server always shows cloud intel down

« on: March 27, 2023, 09:53:49 pm »

Hi

I have found the issue. I normally check things from my phone as its just easier for me but I see now that checking from your phone produces different information for the zenarmor plugin, one of the bits of information being that all the servers are down. I happened to rarely be in the web interface from a pc and noticed everything was working that tipped me off. I believe I did not need to actually reinstall the entire package either and this was done based on the information being wrong displayed when using safari on an iphone.

Zenarmor (Sensei) / Re: My server always shows cloud intel down

« on: March 27, 2023, 05:36:53 pm »

Hi. No icmp works fine and this started being an issue a few updates ago. It always used to work fine. My entire network goes through my firewall and all traffic so I believe it’s something else.

Zenarmor (Sensei) / My server always shows cloud intel down

Unsure how to troubleshoot this. I just uninstalled and then reinstalled and changed to mongo db in the hope it would fix it but it still shows servers are down for cloud threat intel even in the setup as per below. How can I troubleshoot this? Unsure how to access logs.

General Discussion / Re: Python -- multiple vulnerabilities found on OPNsense to v22.7.9_3

« on: December 12, 2022, 02:32:15 pm »

You have to wait for an update to opnsense. When a problem is found there is a period of time that must pass between a solution being found to mitigate it and then that solution to then make it into the various applications that use it including opnsense so you are being informed of an issue in case its such a problem that you need to make another arrangement because you cannot wait (ie pay someone to code a fix for you immediately because its so critical no waiting is possible). Or like the rest of us you can wait if you are not in that situation.

Zenarmor (Sensei) / Re: Blocking quic in policies also blocks whatsapp messenger voip calls

« on: December 04, 2022, 01:46:21 pm »

So far adding the following IP's to zenarmor whitelist/exclusions seems to have fixed whatsapp:

1    102.132.100.62       
2    102.132.99.62       
3   Invalid, something else for different purpose.
4    157.240.19.52       
5    157.240.229.62       
6    157.240.240.62       
7    157.240.249.62       
8    157.240.254.12       
9    157.240.254.35       
10    157.240.254.62       
11    157.240.254.7       
12    31.13.66.53       
13    31.13.71.48

Zenarmor (Sensei) / Re: Blocking quic in policies also blocks whatsapp messenger voip calls

« on: November 28, 2022, 10:05:53 pm »

Yes I agree that opening up udp443 is 100% going to make you vulnerable to dns over the same UDP port if the same destination IP has both services available on that endpoint. This is always the struggle and compromise, but in some cases it is required that the functionality can take prescience over the possible risk of allowing the traffic. This is the situation I am in since whatsapp traffic must flow, even if it means allowing quic traffic (risk is accepted due to compatibility taking precedence).

As it happens I am when a user makes a whatsapp call, if it has an issue I am now checking the logs at the exact time, finding the IP's and adding then to the whitelist for zenarmor. This is similar to what you would do your side but has the disadvantage of nobody else in the world being able to benefit from my capturing of IP's and sharing that information.  So while eventually after a few months the situation will get resolved or me, nobody else is assisted by this method.

Yes I was hoping zenarmor had a list of ips that needed whitlisting because otherwise how can I predict what they are?

Zenarmor (Sensei) / Blocking quic in policies also blocks whatsapp messenger voip calls

« on: November 26, 2022, 03:24:34 pm »

While blocking quic (under the media streaming policy) does precent dns over quic from working, it also blocks whatsapp audio calls as they use udp 443 also for their calls. How can I allow whatsapp calls while still blocking quic In general? Unfortunately the current rule is too blunt and instrument so I have had to turn it off as whatsapp audio calls are used on the network. This exposes allowing all quic traffic however.

Kind regards

General Discussion / Re: How to block every DNS Request on any Protocol and Port

« on: August 28, 2022, 04:55:38 am »

I do this more simply thusly:

1) Outbound NAT rules to redirect port 53 TCP/UDP to Pihole (Log to locate devices trying to bypass your DNS and remove them from your network).
2) Outbound NAT rules to redirect port 853 TCP/UDP to Pihole(Log to locate devices trying to bypass your DNS and remove them from your network).
3) Zenarmor tick rule to block DNS over TLS (Zenarmor has a logging interface automatically)
4) Zenarmor tick rule to block DNS over HTTPS
5) LAN rule to block 8853 UDP out (Dont bother logging any chrome browser will trigger log).
6) LAN rule to block 443 UDP out (Dont bother logging any chrome browser will trigger log).
7) LAN AllowList Alias to allow out CND networks if required
8 ) LAN BlockList Alias to block outbound IP's on lists (LOG THIS RULE SO YOU CAN SEE WHEN IP's BLOCKED):

With this combination I have not been able to find a way to bypass the block unless an IP is added to the allowlist (required if you want to access a site that is a CDN).

I occasionally update this page with new IP's or lists I find (the DOH stuff is near the end):

22.7 Legacy Series / Re: lack of support for opnsense hardware

« on: August 15, 2022, 05:12:56 pm »

I recently purchased an opnsense appliance for a client.  It appears 1500 dollars was not spent wisely.  it appears 22.7 is not supported on official hardware as their fix for any problem is to reinstall 22.1.  Right now the only email contact i can get to is sales....is there an actual support mailbox at the parent company?

You should be running the business version in a business setting, or doing extensive testing prior to deploying updates yourself. You are given choices to ensure safe upgrade (latest business version is based on 22.1.7 as of this message) or you are given the choice to do this yourself for free (cost is your time). You must choose what is appropriate for your use case. That is fair, considering they are giving you the choice to use the software for free or pay and have them test it on your behalf. We have to be reasonable here. I personally find this arrangement extremely reasonable and cost effective.

I guess you are right, then I dont know. I did notice you can also specify a port on the domain overrides by using <ip>@<port> so you can change the port there also.

Development and Code Review / Re: Redundant domain override pages in Unbound?

« on: August 11, 2022, 02:54:20 pm »

They do 2 different things. Domain overrides tells unbound to locally resolve the domain to whatever you set there. Query forwarding forwards the query to an upstream dns server or internal dns server that can be administered and have record values change by someone else or you without intervention on the unbound side. There could be many reasons for this eg: someone runs an AD install and needs unbound to be able to resolve dynamically created records that appear via DHCP registration internally etc or any number of reasons like that.
