you bring that up about tun host and all. after further

Yup -- and that hugeness is much related to the
symbols that make gdb functional. If you want to give
up on gdb much can be stripped to result in a smaller
footprint.<br>

So does that mean that the [?tun ==> host ==>
forward ==> gateway ==> ISP ==> firewall
==> host ==> ?tun] chain is working for you? Or
do you ping from the host?<br>

Perhaps the encap feature is not encapping? Does the
jnos "trace" command(s) directed to a file shed light
on your missing traffic?<br>

There are a few wrinkles that jnos mounted on Linux
[or any other host OS for that matter] provides.
Anyone who grew up on a DOS platform does not
experience the "virtual" thing. Takes a little head
scratching...?<br>
<br>
Best of luck.<br>
