[SOLVED] How to bind a L2 RED tunnel to a specific WAN uplink?

Hi all,

we could implement a basically working L2 lan interconnect with a UTM9-UTM9 RED tunnel. There are two problems for which we need a solution:

1. the RED server site has 3 WAN uplinks. We would like to bind the RED tunnel to a specific WAN uplink. I tried a multipath rule, like shown in the attached image to no avail.

EDIT => for the DHCP problem I created a separate thread:

2. there is a dhcp server present at one end (internal lan behind the RED server), which doesn't work at the other end (internal lan behind the RED client)

Does anyone have hints for solving our issues? Much appreciated :)
