no, no.  I said...

# tcpdump -i eth0 -n ip host 65.188.xxx.xxx and not ether host 

thats all one line.  the first xxx.xxx would be replaced with those 
fields from your IP address not the gateway, and the latter 
xx:xx:xx:xx:xx:xx would be replaced with the MAC address of your ISP's 
default router, as discovered via the other command I listed.

I guess this is just too complicated to do over email...  I recommend 
you find someone local to you who is versed in network troubleshooting.
