I just setup a new custom DDNS account with DynDNS, and got the following error on WRT54-g v8.00.0
"Name resolver fail, DDNS update fail!"
I sent DynDNS an email and they said it was not their problem, that I needed to contact Linksys.
I got a similar error on a trial TZO acct: "TZO echo server update public ip fail"
ISP is Cox Cable, Fairfax, VA Cable Modem: Scientific Atlanta DPC2100R2 MAC: 001AC359F962
Is it possible that the ISP is blocking this transaction? Suggestions on how to solve this problem? I really wanted to use the router rather than running some client on one of my machines on the network if possible.
Most likely this was a local DNS issue. If both TZO and DYNDNS didnt work and stated a failure, the local DNS (your ISP's DNS) could have been having problems. This could cause the router to have trouble finding the domain name pointing to the TZO echo servers and thus causing the failure. I'd reboot the router or try to re-save the settings and see if this fixes the issue. Please re-open your TZO Support ticket on our helpdesk if you continue to have problems with this. You can also try updating the firmware (if there is a new version) and see if that helps
OK, so I have had email dialogs with both TZO and DynDNS, and am now convinced that the problem is a bug in my new WRT54G v8.00.0
QUESTION FOR LINKSYS: Is there some way I can get your product to work as advertised? It is supposed to work with DynDNS but doesn't. They checked their logs and no traffic of any kind ever made it to their server. I've confirmed with my ISP that they do nothing to block DDNS. The only firmware update available is 8.00.2 and it says nothing about fixing DDNS.
I have the same problem with a version 6, firmware 1.02.5. I tried changing the ping from 5 to 10 and it worked with mine as well. I hope it "learned" something, I don't want to have to do this every time my IP changes.
