IPSec tunnel working, but no ping or DNS
-
Hi,
I'm in the process of configuring IPSec Access on our pfSense (Version 2.3.2-RELEASE-p1).
The connection comes up fine and I can access servers via RDP, SMB and so on.
However, I don't get any ping or DNS replies - neither from pfsense nor from any internal server.
I made a firewall rule that allows any traffic from IPSec to anywhere. And I configured pfsense's DNS resolver to answer on all network interfaces. Still no luck.
Any ideas?

Double check you are allowing any IP traffic on the rule. It sounds like you may have selected any TCP.

Indeed, I had only allowed TCP+UDP. Now both work. Thanks!
Just out of curiosity: shouldn't DNS work when TCP+UDP are allowed? -
DNS should work if you allow UDP. Not sure what your issue was, but at least it works now.
