22.1 Legacy Series / Re: TCP stream stops being routed

It seems to be more tied to total bytes sent than to time (definitely wasn't repeatable)

Either way, I don't need the flows to be asymmetrical so I can solve my problem by just routing through the box.

That's a great observation - 192.168.2.23 also had an interface on vlan100, which resulted in the return traffic being sent directly on vlan100.

It makes sense that it works initially, but I guess something is happening on opnsense that results on the flow being invalidated maybe since it never sees the return traffic.

If I remove/disable the second interface and all the traffic goes through opnsense it works as expected.

22.1 Legacy Series / TCP stream stops being routed

« on: February 19, 2022, 10:39:58 pm »

Hello, I'm having some connection issues between two vlans for which OPNsense is the router.
I believe (but am not sure) that this started with the upgrade to 22.1.

I'm running OPNsense as a VM, with a network card being passed in via PCI passthrough.
It's a router on a stick with a bunch of vlans on a trunk port. The relevant ones for this path are
 vlan 100 - 192.168.0.1/24
 vlan 102 - 192.168.2.1/24

Both vlans are dual stack, using a delegated prefix from upstream.

When I SSH from a device on vlan100 (192.168.0.53) to a device on vlan102 (192.168.2.23) using IPv4 the connection works for a little bit before hanging, and eventually disconnecting.

I have attached packet captures for both interfaces which show packets making it in both directions just fine for a while, but after frame 76, nothing makes it out vlan 102.

When I ssh over v6 between the same two hosts the connection seems unaffected.

At first I thought his might be arp related, but watching the arp table on opnsense shows no issues.

Any ideas for what I should be looking at next, or how I can debug this?

Been running 20.7.2-netmap for these drivers pretty happily for a bit now.
