Windows 2000 Network, Routing to external site of same domain name as internal network
Posted on 2004-04-08
I have three offices, one in London, Paris and Munich. These networks are part of the acompany.com Windows 2000 domain. The London office is connected to a US office over a 256K Frame Relay line.
Our US counterparts, in the same domain, have a website, hosted on a public facing IP address.This is accessible from the outside ok. The address of the website is myweb.acompany.com
The website can be accessed fine from the outside, fine from within the UK office, but not from within the Munich or Paris offices. Munich is connected to London via PPTP tunnel between Watchguard firewalls at each end. Paris currently has a PPTP connection to the UK Watchguard set up from a server in the Paris LAN.
We use an internal DNS server in the UK, which resolves names ok. I have set the German servers to use that DNS server, this is fine and an nslookup reveals the correct IP address for myweb.acompany.com Have done the same in France.The France server gets to the website ok. The German servers do not. No clients in the Paris or Munich offices can get to the website.
I think its either DNS or routing, not sure which, any help is appreciated.
