hello!
Assuming you will be using ipsec tunnel mode, you have
to specify the -p option with 50 as argument, i.e.
ipchains -A input -b -p 50 -s .....
-p specifies the transport layer(?) protocol, for
which ipsec is 50.
To my understanding, you won't be dealing with
application layer ports (e.g port 80 for http, 23 for
telnet) since ipsec operates *below* that
layer(transport if i'm not mistaken).
A colleague of mine found this out on a web page
somewhere.
