Linksys Wish-list

Seeing that Linksys keeps adding (unsupported) features to their routers, here's a short list of features I'd like to see added:

External IP address filtering. Since the router can already block internal IP addresses from getting out, it should not be too hard to block external IP addresses (or subnets) from getting in! This has to be done so that the external IP filter overrides everything else. If you're on the ban list, your connection should be dropped regardless of port forwarding.
DHCP reservations. The ability to specify that one computer always gets the same IP address via DHCP can be very useful. Makes it easier to handle static IP addresses without having to deal with changing DNS server addresses or gateway addresses.
DNS settings for DHCP. The ability to specify DNS server settings to be handed out by the DHCP server would be handy for those who have an internal DNS server. Although you can hardcode the DNS servers on the Setup Page, duplicating these fields on the DHCP page would make it easier.
Please fix the IPSec pass-through!
Port translation: The ability to accept connections on one port on the router and direct it to another port on the server. This way, quick fixes can be done on the router rather than re-configuring server software.
