I am about to try VFX, and with all going well moving to Fusion. In the meantime I've been running the Linksys SPA2102 I've bought. My network consists of ADSL --> Dynalink RTA1025W (192.168.1.x) --> Linksys SPA2102 (192.168.0.x) --> Linksys WRT54Gv8 (10.1.1.x (currently running dd-wrt firmware)) --> Xbox/PC's. Our household has 2 Xbox 360's connected to Xbox Live. The routers are all on DHCP.
Before the SPA was introduced all was well. Simply introducing the SPA resulted in regular & frequent disconnections from the Xbox Live service. I tried setting up Port Forwarding (ports 88, 3074 UDP, TCP) on the SPA (the other two routers use UPnP) but this didn't seem to make any difference. So I have set the WRT54G to be in the DMZ zone on the SPA, and this *seems* to have cured the Live dropping, but I am wondering if this going to affect the quality of the VFX/Fusion service. Can anybody offer any guidance?
