If trouble is encountered when attempting a connection from an internalCisco VPN client to an external host, (e.g. a workstation with the Ciscoclient is trying to get out through a pfSense® firewall to connect to a“foreign” site), then try the following.

Workaround¶
First time posting here, I signed up to ask this question after a good search around. I also use Cisco AnyConnect VPN on a work laptop behind a pfsense firewall at home and the scenario is very similar to a post on this forum i.e. If I use a simple device such as an ISP provided modem/router, 4G nighthawk or hotspot'ing to the phone all is good. Is there a way to connect pfsense with an Anyconnect server? No, that's Cisco proprietary. But openconnect works, at least for me on Linux, and from what I gather it's available for FreeBSD too.
