Weird ping problems

[danielrichman]

Guest VMs with public interfaces can't ping hosts on the internet? They can connect just fine though.
tcpdump on host shows packets out and nothing back.

This seems to affect a VM running on 164.39.7.115, and doesn't affect a few other IPs I tried (not an exhaustive study though). Nominate @Upuaut ? Any weird rules affecting .115 ping replies?

Will check on return. What's actual issue no ping replies from 115 ?

I have 3 VMs, pub pub2 and pub3 on .116, .117 and .115 respectively.

All three can open HTTP connections to (say) google; wget -4 google.com works.

Only pub and pub2 get replies to pings sent to (say) 8.8.8.8;
test-pub3$ ping 8.8.8.8 does not work.

Ok will check when back Sunday evening.

Fixed. You had something on .115 before that got compromised Looks like I'd
killed it on the firewall before disabling the entire interface. Just
forgot to remove the rule.

Sorry.
