IPsec aggressive mode support

[sonofdelphi]

Hello,

I am doing a comparison of VPN solutions for a client of ours who wantsto deploy a Software VPN. Before making a recommendation, I'd like to know the following-

1) Does Wingate VPN support Aggressive mode IPsec?
2) Or alternatively, does the Wingate VPN Client be used to connect to Cisco router which is configured in IPsec aggressive mode?

Regards,
Thomas Jacob

Hi

WinGate uses a proprietary VPN tunnel format.

This is mainly because at the time we designed it (about 3 years ago), noone was doing NAT traversal with any VPN solution. We saw this as a key requirement, and quickly realised the only way to do it was by using UDP traffic. IPSEC didn't support this at the time, so we had to go with our own tunnel packet format, and command protocol.

What it does mean is we get an extra 50 bytes payload per packet than IPSEC does over UDP.

Encryption we use is Twofish, 128 bit. Control channel uses standard SSL.

But the short answer to your question is that no, WinGate won't connect to your cisco IPSEC VPN.

Sorry!
