Hello Folks, I'm having a network problem right now with my firewall. Would like to seek your expertise on this matter.
Given: INTERNET | DSLMODEM (public ip) 10.10.10.177/255.255.255.248 | LINUXFIREWALL (untrusted) - eth0 10.10.10.178/255.255.255.248 (dmz) - eth2 10.10.10.179/255.255.255.248 | DMZHOST 10.10.10.180/255.255.255.248 Routing in LINUXFIREWALL is as follows: Destination Gateway Genmask Iface 0.0.0.0 10.10.10.177 0.0.0.0 eth0 10.10.10.176 0.0.0.0 255.255.255.248 eth0 10.10.10.176 0.0.0.0 255.255.255.248 eth2 10.10.10.180 10.10.10.179 255.255.255.255 eth2 Routing in DMZHOST is as follows: Destination Gateway Genmask Iface 0.0.0.0 10.10.10.179 0.0.0.0 eth0 - I can get to LINUXFIREWALL from the world and vice-versa. - net.ipv4.ip_forward is already enabled (1) - No NAT for DMZHOST in LINUXFIREWALL - From DMZHOST, I can ping out but the ping reply could not reach DMZHOST. - Just as the ping goes, so does any other service.
