[j-nsp] building a gre tunnel between two juniper boxes (one behind a NAT)

[Simon Chen]

Hi all,

This might be a stupid question...

I am trying to configure a GRE tunnel between two Juniper routers. One
is connecting to the Internet with a public IP, the other one is
unfortunately behind a broadband router --- this is a temporary setup,
but I need to get it to work...

What is my best option to build a GRE tunnel betweent these two
routers? I am not sure if GRE would still work if one side is behind a
NAT. I can potentially make the second router into DMZ, but it must
run a dhcp client, which I don't think it's there...

Thanks!
