Ssh connection hangs with static route

giulianoz

Hello,
on 1.2.2 I have set a static route to a test network:
linux client <-> lan:pfsense:lan<-> lan:internal router:lan2<->linux server

from the client I can start an ssh session ang give commands to the server. after some seconds however the session freezes. If I set a static route on the client (same gateway set on pfsense) the session works fine.

I've set the Bypass firewall rules for traffic on the same interface, but nothing changes
No logs on the pfsense :(

any idea on what's going on ?

thanks

I'm sorry to bump, but …

on the pfsense I have a static route set for network 10.0.1.0/24 -> gw 192.168.1.111

if I add a static route to the client (route add -net 10.0.1.0 netmask 255.255.255.0 gw 192.168.1.111) everything works

can you give this linux client <-> lan:pfsense:lan<-> lan:internal router:lan2<->linux server
with IP addresses?

giulianoz

sorry for the long wait before the answer. I have not noticed the reply :)

linux client <-> lan:pfsense:lan<-> lan:internal router:lan2<->linux server

IPs are:
192.168.1.100/24 (client) <-LAN1-> 192.168.1.254/24 (default GW) <-static route to 10.0.1.0/24-> 192.168.1.111/24 (internal router) 10.0.1.254 <-LAN2-> 10.0.1.30 (server)

thanks
