pfSense doesn't route PING replies from one of subnets

dimskraft

I have the following topology

From myhost computer I am trying to ping router1 and ping router2.

During ping, I am doing tcpdump -n -i re? icmp and for pinging router1 I see both requests and replies in both re1 and re2. But while pinging router2 I see replies only in re3, but I see only requests in re2.

How to explain this?

I think I'm having a similar issue. I haven't done any packet traces yet, but I can ping from LAN1 to LAN2 but not from LAN1 to LAN3. I can get to both LAN2 and LAN3 externally, So I'm very confused as to why there is a blockage...

I had a similar issue on an opnSense setup but wasn't impressed with the setup/configuration.

Thanks!

You guys set up ACL for pings right to allow them? Run a tracert command and see when it stops, that should be the device with the configuration issue.

This is probably a routing issue.

Both routers, router1 and 2, need a static route pointing to pfsense re1 and re2 ips respectively , saying that LAN is behind it.
