Hope this helps...
Initial release (Feb 2000)
1. Manual key exchange
2. Support for ESP tunnel mode
3. Encryption algorithms: 56 bit DES, variable length key algorithms:
Blowfish, RC4, CAST128 and Simple are limited to a max of 64 bits.
4.GNAT Box to GNAT Box support.
Later release (March/April 2000)
1. IKE key exchange
2. Support for mobile remote software clients
With regard to the IPSec VPN implementation in the GNAT Box-
Users on the protected network (PRO) can access a remote network
transparently through the VPN tunnel once the VPN configuration has been
defined. The VPN also can have filtering applied to it. This means that
although you create a VPN tunnel between two networks you can use the
filtering facilities to control access. So you could limit access on the
VPN tunnel by:
- Source IP (remote hidden IP addresses)
- Source Port
- Dest IP (local hidden IP addresses)
- Dest Port
- Protocol (any IP protocol)
- Day of week
- Time of day
All the best.
