Re: POP3 on the AS/400

[Neil Clark <nclark@xxxxxxxxxxxxxxxxxxx>]

If the firewall is NOT sharing the LAN adapter, (which as I said is the 
preferred method), then the only traffic that is hitting the firewall is 
Internet traffic.  The unsecure port would have more traffic arriving on 
it, some of which will go through the firewall, some will not, based on the 
filter rules and services running.
For example,  1000 packets arrive at the unsecure port, 500 of which get 
rejected, (dropped), because of filter rules, the other 500 pass through to 
the secure port.

If you are sharing the LAN adapter between the firewall and your AS/400, 
then you would want the faster card as the internal network connection.
