Re: AS/400 Accessing the Internet

Proxy servers are typically one way devices - to get from the inside out.
To get from the outside-in, you will need your proxy server to support
forwarding.  In this scenario, your proxy server is on the internet at some
IP address (1.2.3.4) and your as400 is on the inside at some private address
(192.168.0.123).  Your proxy needs to forward telnet traffic (port 23) from
1.2.3.4 to 192.168.0.123.  Getting from the inside out from the AS400 can
get difficult - you'll need either SOCKS turned on the AS400 and supported
by the proxy (this will get you telnet and FTP from your AS400 to hosts on
the outside) or a NAT based proxy.

Forget PING.  Pings won't survive the trip out through firewalls.  PING is
only useful for resolving DNS.

If your current proxy doesn't do what you need, send me a private email.  I
am using Wingate for my proxy and it works well for what you are looking to
do.  It's not easy to figure out, though.  I am an authorized reseller of
Wingate and can help you configure it for the AS400 or even build you a
turn-key proxy server for your network.
