Traceroute only shows 2 hops

Hello,

Seems to have a strange issue, I had this for a while, but never got around to fully troubleshoot. I used to be able to do tracert no issues from windows PC and from NIX* machines. I usually used MTR from nix machines... bit lately I only see 2 hops, my Astaro which is Gateway, and then the destination, nothing in the middle to do any kind of troubleshooting.....

I checked the ICMP settings and they are what they always were, Global = "Allow ICMP trough gateway", Ping setting = "Ping from gateway" and "Gateway forwards pings", tracert settings = "Gateway forwards traceroute", pinging from the astaro shows me all the needed hops, Im not sure what I`m doing wrong or how this stopped working, but what can I do now to get it fixed ?

Please help TIA !

Works just fine, showing all the hops.

But all internal hosts, windows, NIX and embedded devices all show just 2 hops.

Does doing #1 in Rulz give any hints?

Hello,

Checked all the logs, and I dont see anything strange... I think it is ICMP related as linux UDP traceroute seem to work, altho showing a lot of *** in the middle.

I cant understand whats wrong with my ICMP setting, or when did it go wrong, this used to work just fine....

If it works with UDP and from the command line on the UTM and you're not seeing blocks in the Firewall log, then I'd suspect something outside your control.

Just very strange that something would be doing this, now that i`m thinking about it, the command line on UTM it self is using UDP also, I`m going to try with ICMP and see if it does it, I did have an upgrade to FIOS gigabit, with a new ONT installed, maybe its blocking ICMP, just find it very strange...

Thank you for your help

It's currently a known issue on Verizon's network and normally trace routes will show all hops. There's no ETA on when it's going to be fixed but rumor is it's related to IPv6 being rolled out.

FInally Found that Info... I didnt get IPv6 rolled out either, or sophos is not picking up an address (ipv6 is on)....

Love it, how verizon is just able to do what they want.
