Hi David, check out page 28 of the Lync deployment guide:

You can set up the next hop in Network>Routes on your Edge BIG-IP.

Hmmm, so that "worked" but then broke my internal skype services. So basically, I can now set the default gateway to the self IP address i set on on my F5 and i can access external networks through it, but it immediately stops my test clients from being able to log into Skype for Business. The instant i set my default Gateway back to my router, as it was before, everything starts working again.

 

Any idea why all of a sudden changing the gateway would result in Skype clients stopping being able to connect to Skype? The servers can still ping the clients and the clients can still ping the FE servers and the load balancer itself so it's not causing any breaks in network connectivity that I can see. Any advice would be appreciated. thanks!
