Hi. I've just put a dual WAN 2955 router on my network and all is fine with the sole exception of my son's PS3.

The PS3 network settings have a static ip and only use a single WAN connection for simplicity. uPnP is enabled on the router and the PS3.

I've played around with various MTU settings on the router and the PS3 but to no avail.

I'm getting the NAT type 2 warning from the PS3 diagnostics regarding large packet fragmentation but I don't seem to be able to rectify this. The relevant setting on the router is enabled to handle large packets.

Any thoughts about what else I can try please?

thanks

Rob
