So why do you suggest to ping the ISP's gateway, which is a router ? By the way, AFAICS, the OP did ping his own Debian router and a Google server, not any ISP's router. > Interesting, much better: What is much better ? > --- 68.86.118.57 ping statistics --- What is that address ? > 10 packets transmitted, 9 received, 10% packet loss, time 9017ms > rtt min/avg/max/mdev = 28.711/57.428/109.753/28.626 ms The average RTT is still ~60 ms. > So, based on the better ping to the next hop after my router, Better than what ? > why (how) > would something be distinguishing between the router carrying out the > ping, and something behind the router? In the old days some ISPs have been known to try to detect multiple hosts behind NAT with variations of the TTL in packets. > Can I mask it from doing so (if that's the problem)? You can rewrite the TTL with iptables. Note that traceroute won't work any more.
