Hello,

we use a Pix 515 with software 7.0.2 to accept VPN-Clients. This works fine for
clients that come via fiber networks even from far away. But it fails with
clients that come via modems. Any ideas?

Regards,
Christoph Gartmann

The modem clients must be going through some other equipment before
connecting to the PIX -- for example, equipment that is running PPP.
Something along the way might be interferring; there are a lot of
different possibilities.

Which VPN protocol are you trying to use for the modem clients? Does
it happen to be PPTP?

Not that I am aware of. It is the CiscoVPN-Client on Macs and PCs, none of them
works.
