PDA (micorsoft) to VPN RHEL4
 

Hi all

I have a bit of a strange problem.

A PDA (XDA IIs) running Microsoft Mobile was connecting to a RHEL4 AMD64 server via VPN with no problems. Running Poptop 1.3.0

This VPN connection no longer works. I have double and tripple checked and I cannot find any change.

Laptops (windows) can still connect to the VPN tunnel.
If I turn off require-mppe-128 then the PDA will connect again. Of course I dont want to do this.

I have spoken to o2. They tested my tunnel with one of their PDA's and it wont connect either.

I hope someone can help me.


Cheers

AaronJ
