Cisco Pix 501 VPN not working after changing ISP
Hi All
I have a problem with a Cisco Pix 501.
My customer has changed ISP's and i have reconfigured the Pix to use the new ip addresses etc, all the inbound rules appear to be working for SMTP etc but VPN isn't.
I don't really know the pix too well so was hoping someone could see the problem.
Running conf below, i have substitued their new IP addresses for xx.xx.xx.000 for security reasons!

There is one other thing that has changed, the firebox was connected to the internet via a Speed Touch which was knocking on a bit, so that was replaced with a Zyxel, which had firewall and nat disabled on it (this is the configuration used with Watchguard fireboxes).
Is anyone aware of any issues with Zyxel's?
Also how to i remove the old access-list entries?
