Multiple Printservers Behind Linksys wireless Router

[junkoplenty]

I have a functioning network using a linksys wirelessg router. I have one printer using HP Jetdirect 610 (the wireless one) working, and one printer connected to the D-link usb print server. Both work when connected to the network, however only the JetDirect server works when I use port forwarding, HP using 9100 port and the other using 515. I need to be able to print to both printers from outside of the network, can anyone help?

Where did port 515 come from?
Is this a value you set yourself?
The default should have been RAW on port 9100

Port 9100 is the port the jetdirect printer runs on, port 515 is the port the DLink printserver runs on. To setup the Jetdirect printer, it uses the ip of that printer as a networked printer. The DLink requires that you create a LPR TCP port on 515, then set it up as a "local" printer.

It would help a great deal if you specified the specific D-link print server.

The one is used as a reference device was a DP-311U, and its settings are RAW at port 9100.

By the way, this is not a Linksys router issue. It is solely a D-link issue.

Actually its a dlink 301u and it does insit on using LPR mode when you set it up. That port is port 515 not 9100. If it were 9100, would it be possible to set up 2 printers with separte IP addresses behind the linksys router, forward port 9100 to both ip addresses and be able to print to both printers from in front of the router?

Not, not two port forwards on the same port.
And thank you for the product details.

If it is LPR behind NAT routing, I honestly am not sure how to resolve this. I hope brighter guys than I can chip in.

I can't think of a reason why it wouldn't work, but home routers are, shall we say, limited in their troubleshooting and debugging ability.

As a starting point, I would forward the lpr port to a computer and then run Ethereal or tcpdump to actually see if the router is forwarding the packets correctly.
