Hopefully this is an easy question.... I''m using a leaf router (bearing) running shorewall. Three interfaces net, loc, and dmz. Only one computer in the dmz and its being proxy arp''d. External and internal (net and loc) can reach the dmz but the dmz cannot reach the isp''s gateway and beyond, but can reach a system adjacent to the firewall. HUB adj System -- | _____ |----isp --loc--| FW | --net--| |_____| | dmz | Proxyed System I have the interfaces setup as follows. (ips not actual) Adjacent System IP: 24.2.2.202 GW 24.2.2.1 fw net: IP: 24.2.2.200 GW 24.2.2.1 fw dmz: IP: 192.168.2.1 Proxy arp''d compter in dmz IP 24.2.2.201 GW 24.2.2.1 Config files: Policy No entry for dmz Proxy Arp Address Interface external haveroute 24.2.2.201 eth2 eth0 no Rules ACCEPT dmz net tcp 53,21,22,25,80,110 ACCEPT dmz net udp 53 ACCEPT dmz net icmp 8 ACCEPT net dmz tcp 53,21,25,80,110 ACCEPT net dmz udp 53 ACCEPT net dmz icmp 8 ACCEPT loc dmz tcp 21,22,25,110,80 Any help is appreciated Thanks Scott
