the way you connect to your isp is not the key problem.
the key is the version ipf ( v3.4.35) in m0n0 can only handle one pptp 
connection a time. recent version of ipf (4.xx) can support multiple pptp
v2 call-outs but it's said newer ipf is still buggy. so i don't think even the 
upcoming release of m0n0 can support multiple pptp call-outs.

sorry for my poor english
