Ipsec tunnel causing problems with http traffic
I've been using pfSense to create an IPSEC tunnel to a Cisco ASA firewall in our India office for the last 9 months or so and pfSense has been awesome as always.
I've been trying to troubleshoot why http connections over the IPSEC VPN continually time out or take forever to respond. This isn't a big issue as its only for server management web pages so its not like its in daily use. However its starting to get frustrating that in order to access stuff over there I end up having to RDP/VNC into an India server and then use that to access the management web pages.
All other traffic is working perfectly fine (as far as I can tell). I've read a bit about setting the MTU but I'm confused about where best to set this (especially considering other traffic is fine). Does anyone have any hints about where to look for the cause of this fault? Nothing seems to be showing up in either firewalls logs so I'm at a loss about where to look next.
Thanks for your time.
Enable MSS clamping for VPN traffic under System>Advanced. 1400 probably good.
Thanks for the reply, seems to have solved most of the problems will tune it over the next few days to iron out any hold outs.
Thanks again for your time.
