Is this configuration right ?

and I have two questions.

- I want to connect C 2621 using VPN Client . but My IP address is always change because the line is ADSL (DHCP). So How can I change the configuration especially about the "ip local pool" ?

- What port should I open at firewall? Actually I don't know the difference between the TCP and UDP transparent mode.

Thanks in advance...

Use the sysopt permit ipsec command to allow the vpn client through your PIX. I don't think you would be able to connect using the vpn client with a dynamic address. As far as I know, you would need a dynamic address.
