use 4g interface for IPSEC Tunnel alongside normal WAN interface, I want to route RDP traffic via the 4g interface on one UTM?

I want to use a 4g interface that is connected to a 4g modem to connect to a remote site via IPSEC tunnel, I already have a normal ADSL based WAN connection so the 4g interface is to run along side that but just for this tunnel.

I have added the 4g interface and it says its up and running on the dashboard but, the IPSEC tunnel i created using the 4g int as the local connection interface isnt connecting.

Why can I not get any traffic across the 4g int at all? I didn't use the default gateway option as i dont need uplink balancing.

How can I use this 4g int for certain jobs only?

Thanks

OK so i have the 4g int working now i enabled its DG, I have uplink balancing enabled. How do i now get different traffic to go across a separate IPSEC tunnel is it all via multipath? I am going to set up 2 IPSEC tunnels between 2 sites I want one tunnel to go across the standard WAN and the 2nd IPSEC tunnel to go across the 4g int but only for RDP traffic between the 2 sites. Whats the best way to achieve this? Do i use Multipath rules at both ends, what do i use connection based or interface based?

Thanks

Basically what am trying to achieve is to have RDP traffic between 2 UTM's go across the 4g int at one site as its upload is quicker that the WAN int.

Can anyone advise on the best way to achieve this?

John, the only way I know to do that now is with a RED tunnel and Multipathing.

It should be possible with IPsec tunnels bound to an interface and using Static Gateway Policy Routes and OSPF. There's an excellent treatment in German that I haven't gotten around to translating for the UTM Wiki, but the screencaps are all in English: community.sophos.com/.../3.sophos-utm-multiple-s2s-ipsec-vpn-mit-failover-tutorial-de
