IKE Multi site-to-site fails

Good morning,

I am trying to connect to remote locations to our main responder. The
issue I am facing is that I can connect each site individually without
any issue, however, I cannot connect both sides at the same time. The
sides are connect to the Internet via dial-up connections with dynamic
IPs from the same provider. Hence, creating a specific peer rule for
each site doesn't work. Is there a way to have both sites connect to the
responder? With the confs as below, only site B can connect, while site
A fails since it uses the "main_to_siteB" conf on the responder. If I
add quick to the "main_to_siteA" conf on the responder, site A works but
B fails as it uses the site A config. Responder and both initiators run
on 6.6 stable.

Any help or suggestions are greatly appreciated.

Best,

Florian


The iked.conf for responder looks like this:

        local A.B.C.D peer $provider \
