Afternoon!
[Mailserver] - [LAN] - [Aramiska Box] - [Internet] - [Freeuk ISP] - [Dialup Laptop w98se]
1) Our Aramiska box has port forwarding, so we can connect to our internal e-mail server from the internet.
2) We have a no-ip.org entry (wowch.no-ip.org) pointing to the public IP of the aramiska box (123.456.789.101).
3) Our domain server has a zone entry for wowch.no-ip.org pointing to 192.168.0.4
4) The e-mail client on the laptop points to wowch.no-ip.org for POP3 and SMTP.
This means that when the laptop is on the LAN, it will resolve wowch.no-ip.org to 192.168.0.4 and when it is on the internet, it resolves it to 123.456.789.101
Ok, the problem... When using the internet, the laptop just will not connect to the email server, our mailserver traffic log shows it doesn't even try. However, if I telnet to wowch.no-ip.org port 25/110 it works.
If I tracert wowch.no-ip.org and straight after send and recieve in outlook, it works. :/
Anyone have any idea why this may be the case, and more importantly, how can I resolve it?
Cheers
Edit> The laptop is running windows 98 SE, I'll try from my XP machine when i get home tonight.
