Remove my server IP in iptables on ubuntu

Question

I can't access my second server because my first server blocked my second server IP. If I run the IP:

iptables -L -N | grep xx.xxx.xxx.xx             this comes up:

ACCEPT     all  --  xx.xxx.xxx.xx        0.0.0.0/0
REJECT     all  --  xx.xxx.xxx.xx        0.0.0.0/0            reject-with icmp-port-unreachable

the xx.xxx.xxx.xx is the server IP. I have only two rules i.e. to ACCEPT and REJECT for this IP. I want to give access to my server IP from iptables and prevent it from blocking my IP.

Answer 1

Do this to replay the issue

iptables -A INPUT -s 10.64.7.109 -j ACCEPT
iptables -A INPUT -s 10.64.7.109 -j REJECT
iptables -P INPUT DROP

But this won't block 10.64.7.109 and the first rule hit will be accept. You're sharing the output that's got the IP you're interested in and I can't really see why your rules will blocking it.

You can insert another rule at first position which will resolve your issues but without seeing your rules I can't say that it is the best way to solve your issue

iptables -I INPUT 1 -s 10.64.7.109 -j ACCEPT
