upgrade from 2.5 to 2.6 WAN unreachable

[shood]

Hi ,
After a direct update from version 2.5.0 to 2.6, the WAN gateway is unreachable
Feb 15 10:55:17 dpinger 54446 GW_WAN xxx.xxx.xxx: sendto error: 64

This indicates that pfSense cannot communicate with the WAN gateway.

I assume, you did reboot already.
So how is your WAN configured? Which kind of connection is it?

[shood]

@viragomann Thanks
it was working fine before the upgrade
is that any way to reverse update ?

[viragomann]

@shood
Is the gateway within the WAN subnet?

[shood]

@viragomann yes

@shood
The error above indicates an layer 2 failure on WAN.
Presumably the gateway doesn't response to ARP requests.

You can sniff the ARP traffic with packet capture to get sure.

reinstall from a 2.5.2 ISO, then restoring a config from 2.5.2 or earlier (your 2.6 config is not compatible)
With the exception of using ZFS there is no rolling back functionality.

Nothing in 2.6 should do that. You should check the ARP table and run a pcap on WAN to see what's actually happening.

You might be seeing some secondary issue like the hardware support in 2.6 sees additional NICs and your WAN is no longer the NIC you expect it to be.
