RE: Re: [OT]ish Router +modem problem

["Peter Church" <yahoo@xxxxxxxxxxxxxxxx>]

Geoff,



Yes I have realised the problem of the DynDNS not working and need to turn
off - a PC currently does that part.



Everything else seems the same as yours - I have used the ISP DNS servers
and the fixed IP address.  It really is quite frustrating!



I'll try a few more tweaks tomorrow, including turning off the DynDNS just
in case that is messing things up somehow..


Thanks



Pete

I have a similar setup, except instead of 3g it's an ADSL modem. The
only thing I have done that is different is to use a static IP address
for the router WAN and also specify the ISP DNS servers in the router
instead of pointing to the modem. I also don't use DynDns in the router
but instead run it on a PC connected to the LAN.
