Re: what's with VPN trashing my network printer?

[sydnic@xxxxxxxxxx]

What type of gateways do you have on the two networks? Can you use forwarding
queues on these gateways.

I have a client which I support from my office. The client and I have private
subnets. The AS/400 at the client site has same IP address as my iSeries 270
(192.168.1.250)

Both the client and I use Linux PCs as our internet gateways. The Linux gateways
have been congigured to print to the remote site using the Linux apsfilter.
Linux can quite easily be configured to print to a remote machine.

My client's gateway server has been configured with a forwarding queue that
prints to the AS/400 system printer, PRT01.

I use IP printing on my iSeries to print to the forwarding queue on my Linux
gateway. This in turn forwards the print my client's gateway server, which then
forwards the output to the system printer.

I have set this up to allow printed output to go in both directions.

It works like a charm!

Needless to same the firewall at both sites need to be configured to allow this
traffic through. We both have fixed internet IP addresses, so each firewall has
been configured to only accept this type of input from our own IP addresses.
Using dynamic IP addresses fot the internet connection could make this process
difficult to set up.

I don't know if this is useful to you, but this was how I solved this problem.
