I suggest you use

global (outside) 1 XXX.210.223.67 netmask 255.255.255.255

instead of

global (outside) 1 XXX.210.223.67 netmask 255.255.255.248

You can also control outgoing access to specific ports by applying an access-list to the inside interface otherwise you are allowing all outbound IP traffic to the Internet.

everything else seems OK.

I hope it helps ... please rate it if it does

Hi,

You can connect (recommended) your e0 directly to the 1711 router (FastEthernet) via cross-over UTP cable. Or, if you need to use your cat4006 switch, you need to create dedicated VLAN to group ports connecting your PIX (e0) and Router 1711 (use straight-through cable).

Rgds,
