Split Tunneling on Cisco ASA VPN Behind Sonic Wall
Posted on 2014-10-22
I will be helping a friend tomorrow try to figure something out and wanted to see who could help out. Basically, they have a function Cisco ASA VPN behind a sonic wall Firewall. The Cisco was left in place because there were 3-5 users who still use it regularly and because they need it for their VoIP licensing. I am not sure how the two are connected at this point (port forwarding or proxy arp or what). But here are some basic questions we need some advice on:
1) Is there anything inherently insecure about enabling Split-Tunneling in this situation? Why or Why not?
2) Can Split Tunneling be setup on a per user basis, or can it only be enabled for everyone who uses the VPN?
3) How does one configure Split Tunneling using the CLI?
4) And Finally, is there any reason, besides licensing costs, that we shouldn't just stop using the ASA for VPN and switch to just using the Sonic Wall?
