Hello,
I have a strange behaviour with Sophos XG.
It is happening now on 2 sites.
On one site I Have HA (A/P) XG2300 with v19 MR-1.
On second I have HA (A/A) XG2100 with v19.
I tried 18.5 MR-3 with the same issues.
Most of the traffic seems OK.
But some websites are not reachable from LAN and some other start to get ERR_CONN_RST in google chrome after a while.
At the same time in log viewer I get "could not associate packet to any connection" or "Invalid packet." or "Invalid TCP state."
And timestamp/IP dest of these errors corresponds.
Most of the websites that gets error are on Microsoft Azure but not only.
And from the Wireshark trace, they are all TLS1.2.
I have changed FW rules, removed any filtering I think possible.
When connected to the VPN, it works OK.
From LAN not.
Any hint welcome.
Fab
