can't access VPN on PIX 515 through vendor firewall

I have a vendor provided and managed firewall between my internet connection and the internal PIX (which is providing the VPN). What ports/protocols do I need to tell the vendor to open up to allow full VPN for remote users?

Thanks,

Al

Re: can't access VPN on PIX 515 through vendor firewall

Depending on what VPN settings you configed in the PIX.

PIX support Miscrosoft PPTP and standard IPSEC.

Microsoft PPTP using TCP port 1723 and protocol GRE

IPSEC using UDP port 500 , protocol ESP (50) and protocl AH (51).

Ask your vendor open above ports and protocol depending on your VPN config in the PIX.

Best Regards,

Paul Qiu
