I have a client who has 2 remote sites that have a Sonicwall TZ 170 with a vpn connection to the main location. The client has just upgraded with their ISP who also serves the 2 remote connections with a L3 VPN.
The client wants to disconnect the ISP service at the 2 remote sites and access internet traffic through the main location through the new L3 VPN. I totally get that. The client also wants to keep the sonicwalls at the remote site because the units are serving up the anti-virus clients through the Sonicwall.
I am trying to find out if I can turn the TZ 170 into a straight router vs. firewall. There is no need to double nat traffic. I don't want any nat on the remote site sonicwalls. I know this is possible with the newer TZ 100,200 series but am not sure with the older TZ 170's
