Hello,
The setup is as follow:
We have multiple people on our intranet trying to connect to the same client VPN (solution is from Microsoft using pptp)
All of them are going out on the same public interface and they are nated to 1 public ip.
Now only 1 can connect to the VPN in the same time.
After researching a bit, I found out that for the SSG's OS versions 6 or higher, there is no need to do a DIP and can just enable the fuction "alg pptp" and define the pptp service. Did both as described in https://kb.juniper.net/InfoCenter/index?page=content&id=KB12309&actp=METADATA
After doing so non of them could connect to the VPN, checked the firewall and traffic was passing (as far as logs go).
Error message received when trying to connect
If anyone has encountered this issue or knows how to approach it, please let me know.
Kind regards, George
