23.09.1 to 24.03 - Makes bridge unstable
-
@stephenw10 all clients connected to the igc1 (connected to a WIFI AP) had issues. igc1 is bridged to igc0 (LAN connected to a switches) through brigde0.
DHCP (running on pfSense on igc0) then was not picked up on igc1, and not possible to connect to anything... except the AP (ASUS ZenWiFi AX XT8).
Default gateway IPv4 set to a failover gateway group.

I suspect you meant "an asymmetric route" and that was autocorrect...?
Ooops. Yup, can't even blame autocorrect there. Just missed out some letters entirely.

Hmm so igc0 assigned a LAN. igc1 assigned as a OPT interface without an IP address set. The bridge contains igc0 and igc1 but isn't assigned itself?
Are the bridge filtering values set at the defaults?
https://docs.netgate.com/pfsense/en/latest/bridges/firewall.html -
Yes.
They are the default, as this:
net.link.bridge.pfil_member = 1
net.link.bridge.pfil_bridge = 0There are 5 interface assignments
ix3 (WAN 1, DHCP)
ix2 (WAN 2, Static IPv4)
igc0 (LAN switch connected to port, Static IPv4)
igc1 (Access Point connected to port, None)
bridge0 (contains igc0 + igc1, None)Default gateway is set as failover with ix3 as Tier 1, and ix2 as Tier 2.
DHCP server gives IPs to LAN, and with the bridge to the Access Point.
Firewall rules is set on igc0 and igc1. Not the bridge interface. -
Hmm, interesting. And you saw connections failing on both wired and wireless clients?
-
@stephenw10 Just the wireless ones on igc1 failing. The wired ones on igc0 worked fine.
-
Hmm, interesting did it show blocked traffic? On igc1?
-
@stephenw10 Needed to wait until the WIFI was not in use, before I could test again.
Has set the policy back, and the "WIFI " (bridge) is now down again...
Here are some examples from system logs, firewall, normal view:
x May 3 11:41:03 >LAN Default deny rule IPv4 (1000000104) ...:443 192.168.100.55:52372 TCP:SA
x May 3 11:41:03 LAN_WIFI_BRIDGE Default deny rule IPv4 (1000000103) 192.168.100.2:53240 192.168.100.255:7788 UDP
x May 3 11:41:04 >LAN Default deny rule IPv4 (1000000104) ...:80 192.168.100.55:52343 TCP:SA
x May 3 11:41:04 >LAN Default deny rule IPv4 (1000000104) ...:443 192.168.100.55:52340 TCP:SAPing works. 192.168.100.1 is the pfSense box, .2 is the Acccess Point.
Online IPs masked with * -
Update after looking at the blocking traffic.
On the LAN igc0, the allow IPv4 Rule was set to source "LAN subnets", I changed this to Any, and it seems to work as before with the floating rule, also with the interface state policy.
I did have a dropout in a Voice Call over WIFI, but not sure if that was related, so I will be testing more.I am learning a lot new things with this issue.
Edit:
Seems like the issues are back after some without any other changes, so that was probably not it. -
Hmm interesting. What rules do you have on igc1?
The default rule blocking that traffic on LAN is the outbound rule. It's doing so because the state opened by the SYN from 192.168.100.55 is on igc1 and is now bind to that so fails to match reply traffic on igc0.
So you could just set the rule(s) on igc1 to floating binding instead of the global option.
If you're not filtering between LAN and WIFI you could just move the bridge filtering onto the bridge itself so all states are created there.
-
@stephenw10 I ended up moving the static IP, and the DHCP server to the bridge itself. Now everything seems to work correctly with the new policy (has run fine for 2 days).
Old:
ix3 (WAN 1, DHCP)
ix2 (WAN 2, Static IPv4)
igc0 (LAN switch connected to port, Static IPv4) + DHCP Server
igc1 (Access Point connected to port, None)
bridge0 (contains igc0 + igc1, None)New:
ix3 (WAN 1, DHCP)
ix2 (WAN 2, Static IPv4)
igc0 (LAN switch connected to port, None)
igc1 (Access Point connected to port, None)
bridge0 (contains igc0 + igc1, Static IPv4) + DHCP Server -
Yup if you don't need to filter between the bridge member segments that's what I would have done.
