This question is in reference to Atlassian Documentation: How to fix gadget titles showing as __MSG_gadget
The KB specifies to add a rule for localhost.
I already have the following rules:
Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:161 2 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:161 3 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:8081 4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:8080 5 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 6 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 7 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 8 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 9 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 10 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) num target prot opt source destination 1 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain OUTPUT (policy ACCEPT) num target prot opt source destination Table: nat Chain PREROUTING (policy ACCEPT) num target prot opt source destination 1 REDIRECT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 redir ports 8080 Chain POSTROUTING (policy ACCEPT) num target prot opt source destination Chain OUTPUT (policy ACCEPT) num target prot opt source destination 1 REDIRECT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 redir ports 8080
You need to add a REDIRECT rule on the OUTPUT table for localhost because connections to localhost do not pass through the PREROUTING table.
iptables -t nat -I OUTPUT -p tcp -o lo --dport 80 -j REDIRECT --to-ports 8080 service iptables save
