19.7 Legacy Series / Cannot connect to Internet, WAN static IP

« on: August 23, 2019, 04:00:58 pm »

I started the thread with the 19.1 version.
I wanted to give a try to the new version, hoping that something would change but the problem stays.

Link to the old thread: https://forum.opnsense.org/index.php?topic=13914.0

I have this:

Internet -> (93.150.60.50 public) Vodafone FTTH Modem (93.150.60.49 local-ip) -> Deciso OpnSense (192.168.1.1) -> LAN

The current status is:
Factory reset
Routes (attachment 1)
Interfaces (attachment 2, 3)
Status (attachment 4)

What I can do:

I can ping from WAN -> outside

Code: [Select]

# /sbin/ping -c '3' '8.8.8.8'
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.090 ms

64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.036 ms

3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.036/0.055/0.090/0.025 ms
What I cannot do
1. Ping from any LAN PC
2. nslookup from any LAN PC
3. traceroute from the opnsense

Code: [Select]

# /usr/sbin/traceroute -w 2 -n  -m '18'  'google.com'

Using an old connection I managed to update to 19.7.

I updated, reset the whole thing to factory and used the wizard.
I also checked that everything was ok. Now I have the upstream gateway checked.

Still not working.
I am opening the same thread on 19.7 section since I have the right version now.

Using an old still active connection, I am able to upgrade to the next version.
I will let you know if the upgrade succeeds and if everything starts working then.

I am using an old version because it was sold to me like that (deciso hardware), I updated in June or July I think then I switched connection.

I will update to 19.7 when I will get the connection for sure, but I need the connectivity.

Anyway, I already tried testing internet access. No luck.
All my requests timeouts (ping, nslookup, browser).

I cannot find this particular check: Upstream Gateway
Maybe I am setting up the route in the wrong panel?

Anyway I tried and now I have:
WAN_GWv4 gateway: 93.150.60.49 (attachment 1)
WAN Interface Upstream gateway (attachment 2)

I see that the system set some NAT rules (attachment 3)
And i attach the firewall (attachment 4)

I also restarted everything and cleared firewall status.

Now I cannot ping the internet with my PC (but ping works with WAN from opnsense)

Code: [Select]

# /sbin/ping -S '93.150.60.49' -c '3' '8.8.8.8'

It does not work with LAN

My ISP set the modem without a DHCP server, I cannot set the WAN gateway to get an IP automatically.
I set DNS to: 91.80.35.134, 91.80.35.166 (which are default vodafone dns servers), my DHCP should use that.
I tried the 53 port rule. Nothing changed (attachment 1)

Attachment 2 contains my route status configuration
Attachment 3 contains dhcp DNS configuration

No, ping works, nslookup goes timeout.

I save some more information.
I can ping to 8.8.8.8 from my computer but, if i try to ping it from the opnsense server:

Code: [Select]

# /sbin/ping -S '192.168.1.1' -c '3' '8.8.8.8'
PING 8.8.8.8 (8.8.8.8) from 192.168.1.1: 56 data bytes

--- 8.8.8.8 ping statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss

Here I have the firewall log. (attachment)

(attachment 1): new rules
I set LAN Net since there is no "lan subnet" as you said

The result is the same (attachment 2)

I was wondering the same thing.
Unfortunately I am not that proficient with networks so I might ask some help.

I set outbound NAT from auto to hybrid and added a rule but I am missing something for sure..

Update:

I set a new gateway (attachment 1)
and a route (attachment 2)

Now the opnsense server can ping to 1.1.1.1 and others.
I cannot still make it work with the LAN computers.

19.1 Legacy Series / Static IP WAN (no DHCP) -> LAN

« on: August 22, 2019, 12:49:41 pm »

Hello.

I might be asking a really simple one, but I don't see any solution.

My status is:

Gateways (attachment 1)
LAN Interface: 192.168.1.1/24, upstream: autodetect (pretty standard)
vodafoneftth Interface: static ip 93.150.60.49/30, upstream gateway 93.150.60.49
Firewall (attachment 2), pretty standard
DHCP LAN: standard, gateway is empty
DHCP vodafoneftth: Disabled

What I want:
People on LAN network should be able to use vodafoneftth to connect to Internet

What happens:
I can connect to LAN, I get an IP from DHCP (192.168.1.10 in my case) but I cannot anything outsite.
I can also ping 93.150.60.49 from my PC. (attachment 3)

What am I doing wrong?

General Discussion / Re: Dual WAN Loadbalancer: cannot resolve DNS

Yep, I confirm it.
I left a ping console pinging 8.8.8.8 and another console curling amazon.com.
The ping never stops, the amazon.com curl resolves for some time then stops then start resolving again.

I think it is a DNS problem.
If I apply the loadbalancer rule just to my pc everything works fine.
I think it is probably related to the rule that catches any traffic from LAN net (even my opnsense traffic I suppose)

The connection stays alive for like 5 to 10 minutes then it drops for 2-3 minutes then it comes back.
The gateways are stable, this is not a ISP problem.
