Weird IP showing in traceroute

@czujto

Hi there,

I've a weird problem.

I was troubleshooting my vlans and I've noticed something weird.

When I run traceroute to any website or even internal vlan IP, 1st hop is always my UTM gateway IP 10.0.0.1 address but next hop is 10.96.180.1 which I don't recognise. It's not ISP nor one of my internal IPs.

I've country blocking enabled to block traffic from all countries except UK, and allow all outgoig traffic to everywhere.

I've looked up this ip ,10.96.180.1, on who is and it said it's in Durham USA (weird!) Strange thing is that when I block traffic to USA, I no longer can ping, traceroute or browse internet!

I've checked static routes, logs etc. and I can't figure out where this IP comes from.

Any ideas? It's all new to me!

Thanks

K

    Hi K,

    10.96.180.1 is a private IP not routable on the Internet.  I bet that's the ISP's IP for their side of their router to which your UTM is connected.
