Pix was working fine, then one day after I setup access list, which only work for 1 day, there is no more internet access.
My setup is as follows BT home hub is gateway, which port forward port 3389 to a pix 501 firewall, this pix then port forward to my server port 3389 also, that worked for 1 day or 2. The is for learning only, so it is running dhcp, terminal, file, http, servers all at once, the pix wasn't running dns server but in the config it is because i was trying to restore internet connection on a client PC. Also the BT hub powers down every night so save electricity, so ip might change every night, but dyndns updates it to it seems a have a static ip everyday.

config please tell me where i went wrong i will remove dns or dhcpd setting.
