ok guys and gals…
I have a cisco 1720 router connected to and adsl line, this works and i can merrily ping real world IPs.. i also have a sonic firewall hanging of the back.. I can ping from the firewall to the web..
what i want to do is connect an ftp machine into the dmz allow traffic from the wan to the dmz … for uploads and then allow certain trafic from the lan to the dmz to pick up these uploads…
at present the sonic can ping the router interface the machine in the dmz and the lan… but the router can’t get past its wan interface.. it can’t ping the sonic wan interface or the dmz…
now is the cisco or the sonic at fault? i have tried making it an open firewall and allowing all traffic from everyhwere to anywhere… but i can’t seem to get it working.
static assigned Ip from ISP ….. so anyone got any clues what i’m not doing right? or pointers to any documentation?
