Whenever we are connected with VPN client, we have webGUI issue

[eksantrik]

We have pfsense 2.1 loaded on an hp360 g4p. Seems to be working fine expect one thing.

Whenever we use the openvpn to connect to the local network to remotely manage the system, we are having all sorts of issues browsing through the webgui. There is no dropped packets but under the log we have:

We tried to reduce the MSS on pfsense to 1300. Did not work.

Any ideas? Thanks in advance.
