Traceroute only shows 2 hops

yozh

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 !

    What happens when you Traceroute from the UTM?

    Works just fine, showing all the hops.

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

    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
