I think what you posted is just random junk. I don't see anything
that looks familiar.
root@raspberrypi:~# ping 44.26.0.168
PING 44.26.0.168 (44.26.0.168) 56(84) bytes of data.
^C
--- 44.26.0.168 ping statistics ---
7 packets transmitted, 0 received, 100% packet loss, time 6009ms
I also don't receive replies to pings from your ISP address
So we can help you further; Elaborate on " I have added NAT and
firewall rules to send protocol 4 over to my server "
What rules on what type of equipment?

Hello,
I'm setting up a gateway on a linux server, I have added NAT and firewall
rules to send protocol 4 over to my server at 10.0.2.1. Here's some output
from tcpdump. Does this look right to you? Under it I have the output from
ampr-ripd, showing nothing coming in.
