I've got 2811 router with BRI interface. I'd like to use my Windows 2003 DHCP server to assign dial in users IP addresses. On BRI interface I set up: ip address 10.10.16.254 255.255.255.0 encapsulation ppp dialer idle-timeout 180 dialer-group 1 isdn switch-type basic-net3 peer default ip address dhcp ip helper-address 10.10.10.189 no keepalive no cdp enable ppp authentication ms-chap-v2 User is getting IP address, WINS servers address but not DNS servers. If I set up in global config: ip name-server IP_my_name_server then user get this address but if this parameter is not set then after dial in to router this field on client side is empty too. Does anybody know what could be wrong??
