DNS server could not be found - Cisco AnyConnect

[mkyb14]

Looking for some guidance on what I've potentially overlooked.

Wife uses Cisco Anyconnect for medical vpn to citrix url.
VPN connects just fine, but when she now goes to open the URL I get a 'citrix.server.com's server DNS Address could not be found' error

I can switch to a hotspot and do the same steps and she can access the company citrix website.

Just did a fresh pfSense install, so I was guessing this would passthrough and resolve dns like the previous Asus-rt68p would.

Since then I've tried everything from DNS Resolver/Forwarder to disabling pfblocker etc.

Looking for a simple way to understand why the DNS is messed up.  Everything else works with exception of this example.

Thanks.

Mike.

if I change her laptops DNS to have google first, then 192.168.1.1 second it works… looking to figure out how I don't have to touch her laptop and have the box do this.
