have a proj need to use IPsec to do Host to Host communication across the
firewall. I know this is similar to SSH, which I have a little experience,
other than that, I have no clue about, for example, how to set it up on the
two unix boxes.
UNIX A: on company intranet behind the firewall
UNIX B: in DMZ

Actually they are not similar except using some similar cryptographic
algorithms.
IPsec is at network layer and you need to mangle with kernels.
SSH is at application layer and there is not much system-related issues.
IPsec has a built-in filter and network address translation modules,
you don't need another firewall if you have an IPsec implementation
installed on your host.
You may try FreeS/WAN on two Linux boxes. The documention has
a tutorial you
