Sophos Connect and LAN Access

Hello,

Can you please specify the DHCP ranges for the three different VPN you are using? This seems like a configuration error. The other method is to use tcpdump from the console and filter for the internal IP you are trying to get to. See if the packets are received and sent in both the direction.

I did check that as I saw it had been mentioned before.

SSL VPN is 10.81.234.0 Subnet

SC and L2TP both share a 10.3.24.0 subnet but with different ranges specified:

L2TP 10.3.24.131-150

SC 10.3.24.50-70

Hello M8ey,

You cannot share the 10.3.24 subnet between the two. Please change that and it will work.

Regards,

Ramesh

Changed it and no change.

Connects fine but no traffic.

Hello M8ey,

You now need to use tcpdump to see where the packets are getting dropped.

Ramesh

Do you have a simple network - which I would define as a network where the default route (eventually) goes via your Sophos firewall? If not, you may find that your internal router doesn't know where traffic to your VPN subnet should be routed. In that case you'll need to configure your internal router to send the VPN subnet to the Sophos internal interface (the "next hop"). You or someone else might have done this years ago for L2TP.

Hey David

Good points however my XG is the Gateway and no Routers used.

I would expect not to connect if it was that as well where I connect and can browse the XG on the LAN interface but thats all :-(

Hello M8ey,

Are you able to check if the routing table on your machine has been updated after being connected? On Windows, you could run the command in cmd. > route print and check if the gateway has a higher priority?

cmd. > route print and check if the gateway

The 172.20.10.8 is my IP before connecting to the SC

10.3.24.50 is my IP from the VPN within the XG

Hello M8ey 

Is the screenshot taken after connected to SC? It does seem that your local gateway has the higher priority and the network for gateway 10.3.24.50 does not have 'any' route added.
