[j-nsp] ns-50 NAT problem

You can do what you want by using "loopback groups" on the 50.

You define the loopback interface, place the NAT information you want to use
(MIP or DIP) on the loopback.  Then tie the external interfaces to the
loopback via a loopback group.

Hi,

I am having problems configuring a nat on a netscreen 50. Basically I
have two interfaces facing the web with two different types of links and
an internal interface facing the office. What I would like to do is have
the NAT use a loopback IP on the netscreen as the translation IP...but
for some reason this doesn't work. The only way I have been able to make
it work is by binding the NAT IP to one of the external interfaces...but
this is not what I want since I would like my configuration to be
redundant so that if one of my external interface fails...I'm still
online.

Thanks,
Gabriel
