Ronen,
I assume you mean the gwlog.txt file.
This is raw data, designed for a program to read, not humans.
column 1 is the IP address of the gateway columns 2 & 3 are the UTC date and time column 4 is the icmp type, always '3' for 'destination unreachable' column 5 is the icmp code why. '2' is 'unreachable protocol', '3' is 'unreachable port'.
Refer to RFC792 and later RFCs, or the Unix/Linux source code for the meanings of the type/code combinations. Or do a google search for 'icmp type 3'.
For example: 69.85.86.85 17-05-24 02:30:00 3 2
So '3 2' means that the gateway rejected a packet with the message 'unreachable protocol'.
I don't see your gateway '5.29.18.144' in the gwlog file, so it's not rejecting packets from the RIP sender and you're ok. - Brian
