    I have a remote site currently using a DSL connection connected to a
    PIX 501 with a direct VPN connection back to the corporate office. My
    remote site needs to be able to connect (using XP VPN software) to
    another company's network. I can connect to their network if I am at
    home on my DSL connection but if I am behind my Cisco PIX 501 firewall
    I get an error 619. Anyone have any ideas? Any help would be greatly

    If you mean PPTP when you say MS VPN, then the problem is with the pix
    not supporting PPTP passthrough. Sadly, everything but a PIX supports
    it such as the Linksys or Dlink router you have at home - even IOS
    supports it, but not the PIX.

    However, there is hope - it's coming out in the next version.

    The only workaround is to have a static one-to-one NAT with each inside
    host that needs VPN access to a public IP address. Also you will need
    a rule for PPTP (TCP 1723) going in both directions - Just having it
    from the inside --> out won't take care of it.
