Hello friends,
We purchased an RV340 to replace an aging router. The switch was mostly painless except for one issue. Traffic to/from our openvpn service is being interrupted. Our setup is similar to the bottom of this page, we are using a static route to route traffic to 10.8.0.0/24 to a machine on VLAN1 (192.168.0.5). Machines on VLAN1 can ping vpn clients (10.8.0.5) but not the other way around. UDP seems to work both ways fine, but TCP does not. When trying to SSH from inside, I get this message in the logs on the router:
kernel: [87023.255407] FIREWALL:PACKET DROP IN=eth3.1 OUT=eth3.1 MAC=ec:fd:1d:44:8a:21 9c:f6:54:af:e8:a0 08:00:45:01:01:5d src=192.168.0.136 DST=10.8.0.7 LEN=93 TOS=0x00 PREC=0x00 TTL=63 ID=5207 DF PROTO=TCP SPT=34696 DPT=22 WINDOW=229 RES=0x00 ACK PSH URGP=0 MARK=0xff00
I've tried adding firewall access rules for 10.8.0.0 with no change. Even disabling the firewall did not seem to help. Does anything stand out to anyone or is there any advice on what to try next?
Thanks for reading!
UPDATE: It's been a little over a year and after spending some time checking today, the seems to be fixed. My setup hasn't changed much but I have upgraded the firmware on the router twice. Presumably this has fixed what ever the issue was.
