Traceroute - can I set the source range to the VPN clients network range

Hi all,

First time here so go easy on me.

I am trying to see if a route is available from the VPN clients range from the Sophos XG. Traceroute has an option to set a source address but then I attempt it it comes back with:

 

console> traceroute source 10.30.0.20 10.20.10.12
traceroute: can't set multicast source interface

 

Does anyone know if I am doing this wrong or cannot be done?

 

Thank you.

 

Peter

  • I'm sorry if this isn't exactly what you want (bad english from my part.)

    But, you can use the VPN interface as source with traceroute.

    Here's an example of a traceroute to a SSLVPN client.

    SFVH_SO01_SFOS 18.0.1 MR-1-Build396# traceroute -i tun0 10.0.50.11
    traceroute to 10.0.50.11 (10.0.50.11), 30 hops max, 46 byte packets
     1  10.0.50.11 (10.0.50.11)  198.032 ms  64.203 ms  40.030 ms

     

    Thanks!
