I use a Thomson Speedtouch DSL modem to an 10/100 8 port switch then drive a pair of D-Link Gig-E N routers, DIR-655 and DIR-825.
The modem sees two MAC address and offers up 2 IP's.
You can manage them from account web page.
The only way is by using a stand alone modem and a switch as pointed out above. A modem such as the Thompson or ALU. You can't access two distinct IPs with any of the modem router combo units (D-Link 3810 or Actiontec).
Use a modem alone to a switch then to your routers or peripherals.
There is no way to access a second IP with OptikTV. Only the Actiontec will be used or sent out for OptikTV and it can't access two separate IPs.
Since you are provided with an Actiontec as your modem/router with OptikTV, and since the modem is within the Actiontec and is inaccessable to the user, it is impossible to get 2 distinct public IPs with OptikTV service.
There is no place to put the switch to separate the 2 IPs exiting the modem since there is no separation point between modem and router that is accessible to the user.
If you are on Optik and you have an ALU, you can have 2 ip addresses, one for the TVs and one for the PCs, by using a switch and two routers. The problem is that ALU modems are becoming very scarce so in all likelihood, you will be stuck with an actiontec and will only be able to get one ip address.
