IPSec blocking intranet sites
-
Really scratching my head on this, I have 3 IPSec tunnels from my head office (single pfsense firewall) to 3 branch locations, this has been working fine for years, but recently we changed from ADSL to fibre at one branch location, replaced the firewall, everything started off working but over a couple of weeks there has been a cascade failure where the local clients have gradually lost access to the intranet servers at the head office, they are still able to ping the servers, but the intranet pages time out. They can still access an RD server at the head office and the IBM i access is still available, there does not appear to be any problems with accessing the branch network from the head office.
Any suggestions would be greatfully received!
