Re: Fix-for Cisco-VPN-Client

Personally I don't have any problem with the CheckPoint VPN ActiveX SSL
Extender we use at work (I'm gonna try with the client soon), I'm wondering
if that problem is not generated by a setting or a special security feature
in the Cisco VPN Client... and OS detection is not accurate, probably due to
the encryption : here is the results of 2 scans, one over vpn the other
directly on the network. I guess it wouldn't be a good idea to submit this
fingerprint right ?

Here is a fix for Cisco VPN Client using nmap.

Follow these step and you will be able to use NMAP with Cisco VPN Client

  Adresse Internet      Adresse physique      Type
  192.168.2.1           00-13-a3-ec-90-9f     dynamique

2=Get your MAC from your LAN interface in my casse it is
00-13-a3-ec-90-9f

3=Get your IP address from your Cisco VPN Interface in my casse it is
172.24.1.129

Interface : 172.24.1.129 --- 0x80005
  Adresse Internet      Adresse physique      Type

4=Do the next command.

c:\>
c:\>arp -s 172.24.1.129   00-13-a3-ec-90-9f

Try it you will like it.


This is fascinating.  Does anyone if this trick will work for other
interface types not supported by Nmap (dialup/PPP, other VPN software,
etc.)?

Cheers,
