Hi,
I have a Sophos UTM running in hyper-v with 5 physical interfaces.
I would like to add an additional interface to allow only L2TP IPSec connections using an additional line.
(I have the VPN configured and working correctly on a different interface so hoped it would be easy to migrate to the other faster line)
The additional line: - I have a 80/20 VDSL line connecting using an Archer VR2800 - this has wifi and 4 lan ports. I plan to add this connection to the UTM?
The Archer VR2800 is operating as a modem/router and has an external fixed ip "A.A.A.A" and the lan ports have a local subnet 192.168.4.0 via its own DHCP. (All fairly standard.)
I have patched the UTM to one of the lan ports of the Archer...
I have created an interface on the UTM - giving it the external IP address I would like it to use. I suspect the DHCP on the Archer router is stopping this from working?
The Archer does not appear to have a WAN port? I cannot see any bridged mode options on the Archer? can I add some kind of NAT rule in the UTM to allow traffic to pass over the line for VPNs?
Do I need to configure the UTM interface to use a local IP address (192.168.4.xx) and some kind of routing rule to allow the external IP address to resolve?
I Hope this makes sense! Any advice or guides towards the correct method of connection would be greatly appreciated.
Many thanks,
Tony
