Hi all,
I just upgraded directly to the following firmware from 384, so far no issues *fingers crossed* but i am curious on a WAN portion setting, by default the NAT Type was on symmetric but i could not get internet access, it gave me an internal IP (presumably from the ISP) and then dropped 5 seconds later (process repeats), only if i match up symmetric with UPNP on or changing it to Fullcone mode will i get internet access.
Looking at posts online and in the forums, seems fullcone is meant more people with multiple gaming consoles or pcs as it makes it simpler to configure. My question is must the ISP be able to support symmetric in order for it to work without UPNP? also since the router defaulted to symmetric is it because it is better or more secure? Assuming ISP supports either modes, any reasons to use symmetric over fullcone?
Thank you!
