It hangs on verifying username and password and then redials. Where not using
our PIX at the moment otherwise I wouldn’t even bother with PPTP. I can
connect internally via PPTP. The router is an SMC 8013WG. I have everything
in the router set correctly and I verified the setup with SMC. I believe it
is a GRE issue at this point also.
