I'd check your firewall first. Is it doing anything to manipulate the
traffic flow?

Subject: Amazing behavior of VPN Concentrator
Dear All,
I am getting strange problem in VPN Concentrator.
Following are the Tasks
1. Allow administaration of VPN concentrator on PUBLIC interface.
2. Disable http to https redirection ( By default HTTP to https redirection
is there on Public interface)
3.The administration should be port *8080.*
Now I have done above tasks more then 10 times and every thing worked fine
for me. My PC from where I want to access VPN concentrator and VPN
concentrator were in same vlan and every thing worked fine.
Just now I put some routers and firewall b/w VPN concentrator and PC for
testing purpose and tried to access VPN conentrator on port
*8080*GUI(graphical user interface). I can see the login page of VPN
concentrator
but when I enterted username and password. I can NOT login to it. BUT if I
change the port to any port other then 8080 it works and I have no issues
to access it.
My question is that why I am able to access VPN concentrator on port 8080
when my PC and VPN-C is in same subnet (vlan) and WHY I CAN NOT ACCESS
VPN-CON ON PORT *8080* when in b/w I have routers and firewalls.
Any Ideas.
Thanlks
