cisco 1721 triangle whit 2 cisco 800 over isdn 128k

Hi guys,

Im having issue whit my litle configuration, we got 3 router on 3 different subnet that are link together via a ISDN 128k for each (64k per spid), one is working very well no problem at all, bu the second whit same config exept hes on a second subnet, DNS query wont go through anymore, ping loosing packet, hudge delay when using network etc ...

I've called the provider for testing purpose and all seem to be working on their side !
