Using ExpressVPN with F5 VPN

I have a ExpressVPN Aircove router which is connected to my modem and I am connecting my corporate laptop to the aircove router. I have expressVPN enabled on the router and when I try to connect to F5 VPN it is not allowing the connection to go through.

My current setup is as follows

ISP Modem → ExpressVPN Router → F5

Is there anyway to make this setup work? I read it is not possible to have another SSL VPN running with F5, i tried this same setup with Cisco Secure Client and it works fine without any issues.

Are you sure the connection through the expressvpn tunnel can reach the F5 endpoint?

Were you able to resolve this? I am experiencing the exact same issue.

How can we verify that?

No it turns out that F5 will run certain processes on certain ports which conflicts with ExpressVPN. Even if you change the protocol on ExpressVPN certain ports are required to remain open which is taken up by F5. So currently as of my knowledge, there is no way to run both simultaneously.

You should be able to telnet to the DNS name and port of the virtual server from the client while routing through the expressvpn. If you can’t try telnet to the IP instead of name to see if it’s a DNS issue.
