ipsec nat transversal

[SimonChan () lifeisgreat com sg]

Hi fellow wizards,

I have this situaton here :

I have an existing Firewall / VPN gateway and we have remote users vpn
client connecting to it.

We are in the process of putting an additional firewall in front of the
existing firewall.
If both Firewalls are running NAT, can the remote vpn client connect to the
2nd Firewall.

I understand that the term "ipsec Nat transversal" function is required on
the 1st firewall
in order to allow IPSec traffic to pass through.

Is that Correct ?


tks.

Rgds,

Simon
