CentOS 5.8: Cannot NAT Forward for HTTP server...
Hi,
This is an embarrassing question. I can't get HTTP traffic forwarded to my web server behind my CentOS 5.8 firewall. I had this all *working* before I moved into my new place. I confirmed that it is *not* a problem with my cable modem or my new ISP by temporarily making my firewall a web server.
Currently with the rules below, if I try to access my website from an external location (say at work or an internet cafe or my phone) i get 502 bad gateway or timeout.
Below are my nat and filter rules:
Code:
Table: nat
Chain PREROUTING (policy ACCEPT)
num target prot opt source destination
1 DNAT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 to:192.168.1.2:80
Chain POSTROUTING (policy ACCEPT)
num target prot opt source destination
1 MASQUERADE all -- 0.0.0.0/0 0.0.0.0/0
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
Table: filter
Chain INPUT (policy DROP)
num target prot opt source destination
1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
2 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:22 state NEW,ESTABLISHED
Chain FORWARD (policy DROP)
num target prot opt source destination
1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
2 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
3 ACCEPT tcp -- 0.0.0.0/0 192.168.1.2 tcp dpt:80
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
Any help on how to make http forwarding work again is much appreciated. |
