We have two locations with SonicWALL TZ170-series firewalls (“HQ” & “Remote Office”). Both are running CGSS (Comprehensive Gateway Security Suite) which have CFS (Content Filtering Services) filtering content and websites.
The issue is that when we VPN into the HQ network, the HQ CFS policy is being applied to our browsing sessions, which is prohibiting us from going to the sites we need to because they have a different (more strict) policy than we do. I can put my IP in the Exclusion List, but once logged into the VPN, the server (SBS 2k3) in HQ is running DHCP so it just randomly issues me one. Next time I VPN in I will probably be issued a different internal IP.
The HQ has a static external IP. All of the PCs & server have static internal IPs. The Remote Office has dynamic DNS in place.
Are there some rules I can set in the server and/or SonicWALL so that when I log into their network it recognizes us via dynamic DNS and issues us a specific IP or issues a specific pool of IPS to us? That way I can simply put that specific IP or the specific pool of IPs into the Exclusion List and thereby keep our (the Remote Office) CFS policy the entire session.
