Hmm. I executed 'env' in my ip-up script itself and found no
distinguishing info

That might work if you have VPNs going to different endpoints.

I want to have two different setups going to the same service.
One redirects *ALL* my traffic there, while the other only a certain
subsets of routes (which is done in the ip-up script).

However, I cannot in the ip-up script distinguish which of the two
services were called..
