Problem with dynamic IP from ISP
« on: October 19, 1999, 08:43:33 PM »
Hi all,

Thought I'd report on a problem that took us all day to solve, in case anybody else experiences this.  I'm installing an e-smith server in a school in Ecuador.  When we configured the server with a new ISP it would dial and connect but we couldn't send or receive any traffic, except to ping the dial-in server at the ISP.  We finally noticed that our server didn't seem to be getting an external IP address from their dial-in server.  The problem was solved by editing /etc/ppp/options and adding a line that read "noipdefault".  

Now it works great!!!  So far it is much more stable and transparent than the WinProxy configuration we were using before.

Best regards,

I remember seeing a similar problem when I set up a system - PPP
was preferring to use the LAN IP address - which is not routable on the Internet. Joe, I think we should add "noipdefault" to the pppd options line in the diald.conf template - I suspect that PPP will only work correctly as currently configured if the ISP's PPP setup forces the e-smith PPP link address to their preference.
