SSL VPN connects for a second then disconnects.

David Clark

So, I have an XG-135 v 17 and I'm a newbie working with a support engineer who isn't available all the time, so I could really use some help with this.

The SSL VPN is setup on a laptop we use as a remote branch of our business. It supposed to connect back to our XG from a local High School and from that point, the use RDP's to a desktop to run transactions. We tested the laptop by connecting it first to our spare internet connection, which is a separate network and IP address. It connected to the XG and allowed the RDP to desktop with no problem. The staff took the laptop to the HS and attempted to connect back to the XG and it failed with no error message. I was told it never flashed that it had connected and the traffic light icon only went to yellow. When an RDP session was attempted anyway, it also failed. I took the laptop home and tried to connect to the XG from my network at home. It worked fine and connected right away, the traffic light turned green, flashed connected on the screen and I could RDP into the desktop. I figured this could be user error or some issue with the HS network. I let the staff member attempt another connection and it failed the same way again. This time the school technicians verified that there was an Internet connection and that there was an exception in their firewall. The HS uses a SOPHOS UTM running v9. They save the log file on the desktop and it says it briefly connected, 1 sec, then something happened. That is what I'm trying to figure out. Do I need to put the HS public IP into my ssl vpn network policy? Just confused as to how it works in two other places and not at the High School location. I can post the log but I'd rather not if I don't have to.

Thanks,

Dave

    You have a point in XG called "Overwrite hostname" in SSL VPN config. 

    This point is the connection IP for all clients. Do you use something there? DNS Record? Could this DNS record be not be able to resolve correctly to the XG? 

     

    Can you show us the log of SSL VPN?

    Hi,

    Here is the SSL VPN log from the failed connection. I've removed any of my network specific information. I am also using static ip's in a workgroup at our XG location. The other location (where i can not connect from is using DCHP addresses to the laptop. I wonder if this is a routing issue?

    Do you use HTTPs scanning or something like this on the UTM9 site? 

    The connection seems to be there, but the communication looks broken. 

    You could perform a wireshark dump of this and check, what is going on.

    Thats a good point. When I talked with the school technicians, I asked if they were doing any filtering of the Internet and they said that the connection should be passing through the exception that was made in the firewall. This exception, was made a couple years ago when we were using the Cisco ASA 5512x. I asked if it would need updated or checked and they said if I was using the same IP address then it should be fine. I am using the same IP address, we just swapped out the ASA for the Sophos. I will ask them tomorrow morning when school opens. I have a ssl vpn log from my test, when I connect back from our backup connection and I don't see any of this part in it:

    Just to be clear...the UTM 9 site is the school. I used to connect back to an ASA before we purchased the sofos xg-135 for our office. I don't have any access to the school network, all I can do is ask them questions and convey my concerns. Also, I will download a copy of wireshark on the laptop for our next scheduled visit the coming tuesday.

    So, just sovled the issue today. The school was doing application filtering on their UTM. The old firewall rule from the cisco anywhere vpn needed changed. all good. thanks for the help.
