I had a great deal of trouble setting up my DDNS details in setup window. Basically Linksys has not given enough room for the hostname. At the present time I have tested with firmware versions: AnnexA_ETSI_v1.01.6_0209 AnnexA_ETSI_v1.02.9_04 AnnexA_ETSI_v1.03.0_beta4_00 There is only room to write 30 characters and when it comes to a dyndns custom dns account one has to write hostname&system=custom. My hostname plus the added bit required 31 characters! I got round it by filling in the max 30 characters that's allowed and then copying the address link information when I pressed "save" in the DDNS window (one has 5 seconds to highlight and copy!). It looks roughly like this: http://192.168.10.1/Gozila.cgi?DDNS...tname=bla.bla.com&system=custo&hid_ddnsSave=2 You can see that there is no "m" on the end of custom. I then manually added the "m" at the end of "custo" and pressed enter. The 31 characters were accepted!! Why doesn't linksys fix this??
