You port forward from whatever router is the default gateway (whichever one is handing out IP addresses).
As for accessing the cams, I don't know.
If you have multiple routers attached to each other via LAN ports on both, only one should have its DHCP server enabled to hand out IP addresses.
CCTV VIA CAT 5 > 710 WIRELESS BRIDGE > "air connected to" E2000 WIRELESS ROUTER > HARD WIRED TO WIRED LINKSYS ROUTER HARD WIRED TO > CABLE MODEM > OUT TO STREET.[/B]
...THIS BEING SAID, WHICH ONE SHOULD I CHECK FOR THIS DHCP SERVER?
and all devices on the network would get their address from that one router with DHCP enabled.
GEEZ, I THOUGH THAT THE PRINCIPE OF THE ROUTER WAS TO "CREATE" IP ADDRESSES SO THAT MULTIPLE DEVICES COULD RUN WITHOUT A "COLLISION" OF SORTS BECAUSE OF IP CONFLICT.
Then that means the router coming directly off your cable modem is handing out IP addresses.

...so, that particular wired router gets "requests" to it to be forwarded out to the net OR, gets requests from the net to be forwarded to my "network" or both?..or am i still majorly messed up here?
Not really either. Hosts/computers on your LAN broadcast out a DHCPDISCOVER packet through your network. There is a DHCP server on your router that receives this, compares it to the currently allocated addresses, and then sends a DHCPOFFER with an IP address, mask, default gateway and DNS reference back to whatever computer or device requested it.
The requests don't leave your local network, so the router handles them all itself. The router does a similar process by sending DHCPDISCOVER to your ISP in order to get an Internet/External address.
The problem with multiple routers in a home environment by default is that they are not aware of each other and their leases. One router may receive and send the DHCP offer faster than another, but it could potentially be an address that was already allocated by the other router.
Therefore, you would resolve this by only using one DHCP server and disabling the service on the extra routers.
