VPN causing POP3 and SMTP to not work! 500 POINTS!
Posted on 2005-04-21
I have setup VPN and can successfully connect to it. I use remote desktop connection and tightvnc through it.
When I am connected to the VPN, I notice that some employees on the LAN cannot use POP3 or SMTP with their outlook express applications. This doesn't happen all the time. They simply get an error stating that they can't connect to the server. They are able to connect to the internet but not email.
I am pretty sure its an IP address or subnet configuration. The IP Scheme for the server is 192.168.1.x and I have the DHCP assign IP addresses to the clients from the VPN such as 192.168.1.x. Since I am having it address it that way, would that cause a problem. The subnet mask of the server is 255.255.255.0 but the subnet mask of the VPN client is 255.255.255.255.
The only way I am able to get the employees desktop to use email again is by restarting it sometimes multiple times.
I have posted multiple postings about this issue but no one seems to know what the problem is with VPN.
Someone please help.
