IPtables & Sonicwall
 

Has anyone ever had any success placing a sonicwal vpn device behind an iptables firewall? I want to put this device on it's own subnet/interface so it's totally seperated from the regular network when people connect thru the internet to my network, but can't figure out what ports to forward , assuming this will work at all. Your input would be appreciated ;)

i haven't done it but i know its possible
you'll have to add routes to communicate between the two subnets unless you got the money to put routers instead. check out sonicwalls homepage for the port information and setup up iptables to log and forward those ports to the vpn device.
Look on sonicwalls homepage for port information or check your documentation
