I'm having a networking issue that I cannot resolve.
My DirecTV HD DVR receiver (HR21-700) shows a connection to both my network and internet. However, the STB services port (range of 27161-27192) will not connect through my router (linksys E4200) automatically or manually. I can directly connect the receiver to the modem and get it to connect properly. None of my other components (XB360, BluRay Player, two PCs, Wireless Bridge) have any issues. The XB360 and BluRay are both hardwired to the router (as well as the Dtv Rcvr), and have manually configured IPs and DCHP reservations.
I am STUMPED and FRUSTRATED to say the least... Linksys, Dtv, and Mediacom support have not been able to resolve anything.
Manually configuring IPs and port forwarding is about the extent of my networking knowledge... Are there any settings or configurations that I may be overlooking?
The uPnP is enabled, NAT is enabled, and all firewalls are turned off.
