I would do the MOCA bridge solution in that case then if the remote DVR and on screen caller ID are not that big a deal for you. If losing those would be a deal breaker for you then you've gotta get that double port forwarding to work as described in the article.
I use a Netgear wireless as well on the same setup because I dislike the actiontecs and their capability and the features I lose are not important to me.
I'm at a point where I can't spend any more money. If I could I would just buy a larger switch.
The on screen caller ID is not something we use in the house but the remote DVR is very important to us.
I know there has to be a simpler solution that I'm overlooking.
The STB's are being given 192.168.1.100-1.105 If I could switch them to 192.168.3.10 to 192.168.3.15 and set the LAN port of the Actiontec to 192.168.3.1 then everything would be on the same subnet.
