Unable to establish a VPN tunnel

[gdankberg]

I need to establish a client VPN tunnel through an old PIX running 4.2.5. The tunnel will terminate on a PIX 515 running 6.0.1. I tested my configuration through an Internet dial-up account which works great. Is there some configuration I need to do on the older PIX? Any suggestion would be greatly appreciated

You need to open up UDP port 500 (ISAKMP) and IP ports 50 and 51 (AH and ESP).
