General Discussion / Re: GeoIP Not Working?

« on: April 19, 2022, 02:32:17 pm »

I have setup a number of countries that I should just drop

This means you've created an alias with selected countries?
Then you can add firewallrule(s) using that/those alias(es) to block traffick.

General Discussion / Just tried out Geoblocking using MaxMind....

« on: March 01, 2022, 07:36:37 pm »

Turns out that 2! addresses are responsible for 2/3 of the last 5k connections....

A Belarus IPv4 and a Chinese IPv6 (until 2-3 days ago the Belarus IPv4 wasn't there and the Chinese were sitting at about 50% of the connections - seemingly randomly scanning my IPv6-space.....)

45.143.200.114      2192 connections
240e:f7:4f01:c::3   1129 connections

General Discussion / Re: Shodan Blocklist

« on: September 03, 2021, 11:59:18 pm »

I just noticed my first IPv6-shodan host....

Aug 30 08:01:51 mail.vlh.dk postfix/smtps/smtpd warning: hostname editor.census.shodan.io does not resolve to address 2604:a880:2:d0::978:7001: No address associated with hostname

Was wondering how I would add that to the list?
Simply change to IPv4+IPv6 for the rule and add 2604:a880:2:d0::978:7001:?
Or do I need to format it in some specific way? (and can I mix IPv4 and IPv6 in one list?)

21.1 Legacy Series / Upgrade from 21.1 to 20.7.8???

Didn't update my firewall for some time.

20.1 Legacy Series / Adding request options to dhcp6c

« on: June 05, 2020, 05:16:38 pm »

I've switched ISP which should me allow to go native IPv6 instead of via a HEnet-tunnel (which has otherwise worked great).

But - it seems that the dhcp-client is requesting all the needed options for it to work with the provider;

I can get it to request:
Requested Option code: SIP Servers IPv6 Address List (22)
Requested Option code: DNS recursive name server (23)
Requested Option code: Domain Search List (24)
Requested Option code: Simple Network Time Protocol Server (31)

But I also need:
SIP Server Doman Name List (21)  (I tried adding sip-domain-name, but that give a syntax error in the log on restarting the interface)
NTP Server (56)
Dual-Stack Lite AFTR Name (64)


I might need more options - waiting for a complete packetdump from my ISP.


Is this something that wouldd be able to achieve at all?

I'm trying to redo this: https://www.22decembre.eu/en/2018/05/28/dhcpv6-kviknet/ which is preciesly the same ISP - and appearently a OpenBSD-setup - using dhcpcd.

General Discussion / Shodan Blocklist

« on: June 11, 2019, 05:47:49 pm »

Didn't find a recent list of Shodan IPs, so I decided to make my own from my logs....

I use it as an alias (URL Table IPs) and an IPv4 block rule on my wan.

Free for any that want to use it: https://www.vlh.dk/shodan.txt

Last update was einstein.census.shodan.io which started connecting this morning.

If you have any other Shodan IPs, feel free to reply - and I'll add those to the list

15.1 Legacy Series / Re: Request For Testing: OPNsense on FreeBSD 10.1

« on: February 17, 2015, 09:41:31 pm »

Selecting System -> Setup Wizard, Services -> UPnP & NAT-PMP or Status -> Traffic Graph the menu collapses - doesn't do that for any of the other entries... (dunno if that's intentional).

I feel the menu-entries should/could be a bit smaller - I don't like having to scroll through the menues, at least not when scrolling and hitting the bottom of the menu causes the main-page to scroll.

Otherwise I think I'm quite close to shutdown my m0n0wall and replace it with OPNsense - good work

15.1 Legacy Series / Re: Request For Testing: OPNsense on FreeBSD 10.1

« on: February 17, 2015, 08:03:54 pm »

I installed OPNsense-201502140847-memstick-serial-amd64.img on my spare PCEngines APU1D4.
Installed fine and no problems with the initial setup - now I'm starting to configure it to replace my m0n0wall-installation.

I created some aliases and started creating Port Forward NAT-rules (Firewall->NAT) using said aliases. In the rules-list the alias gets prefixed with Array (ie. when I created a Port Forward NAT for my mailhost I see 'Arraymailports' as Dest. ports, 'Arraymailhost' as NAT IP, 'Arraymailports' as NAT Ports).

The rules auto-created in Firewall->Rules are not prefixed with Array.


Back to figuring out to migrate the rest of my m0n0wall-config

15.1 Legacy Series / Moving from m0n0wall to Opnsense

« on: February 16, 2015, 07:11:38 pm »

Hi,

The m0n0wall-project has come to an end and Opnsense was mentioned as an alternative.
I'm in the process of installing Opnsense on a spare PCEngines APU1D4 (1GHz dual-core amd64, 4GB RAM) but I think I might need some help transitioning my m0n0wall-configuration to Opnsense.

Is there any how-to for bridging interfaces?
ie. I'm trying to get re0 and re1 (and later wlan0) bridged - have a 10.0.0.0/23 network running on them and they should respond to 10.0.1.254.

Also, any how-to to setup a he.net IPv6-tunnel?

Alternatively a script to simply convert an exported m0n0wall-config


The installation went smoothly with the OPNsense-15.1.5-memstick-serial-amd64, transfered to an USB installed to mSata - thumbs up
