hi all,

could someone post the port, protocol and incoming IP address for NTL's DHCP server or show me a link to it?
My firewall keeps on blocking it, hence my BB cuts out. Its port 53 isnt it? Not sure of the protocol or the incoming IP though.
TIA
:)

Port 53 is for DNS.

The DHCP port is 68 (UDP).

I'm not sure of the IP of the DHCP server (Can't remember it, & I can't find it as I connect using a Linksys router).

Have a look at these two pages on Robin Walker's CM Tips site, for info on DHCP, firewalls, & more:

DHCP Issues (http://homepage.ntlworld.com/robin.d.h.walker/cmtips/dhcp.html)

Firewall Config (http://homepage.ntlworld.com/robin.d.h.walker/cmtips/security.html#fwconfig)

EDIT: Looking at Robin Walker's site, you may need to add more than just the DHCP server's IP to your firewall's "trusted zone". DNS IP, UBR IP....Lots of info there, & settings for different firewalls.

DHCP uses UDP on ports 67 & 68.

The DHCP server IP varies as they are local to your area.
