The AS5520 SSL vpn works much better than standard vpn clients.

If your network connection is connected to a PIX firewall you can have
the PIX to work as a VPN. This what I am doing with my VoIP softphone
and it works fine.

You only need to specify groups and based on the groups you allow which
network you want him to have access to.

All, I'm hoping someone can help out with some configuration and/or
solution suggestions.  I am on the design team of a VoIP project.  The
solution we are designing has two separate VLANs, one for voice and one
for data.  The only traffic allowed to travel between VLANs is DNS,
DHCP, SNMP and NTP.  The customer is interested in using softphones
remotely (business trips, for example) on laptops only.  What we would
like to do is make it as simple for the user as possible.  What we would

like to do is set up a VPN solution where the customer establishes one
VPN back to the corporate network to check email and make phone calls. 
The VPN server would be attached to both VLANs and distribute the
traffic to the correct VLAN.

Does anyone know of a VPN server that will do this?  Another solution?

Thanks In Advance.
