It seems as if the only solution would be to get your own internet connection. This could be something like a DSL connection with only 1 pc connected to it. Bill

    FTP & Setting up separate network

    Bill, Thanks for reply. I was thinking of communications adapters on As400; may be I could connect something there and create a point-to-point communication! And, be able to open location #1 to transfer reports there, close, open another location. I don't know -- just thoughts coming. PC with DSL is ok except that it still needs to be connected to AS400, and there has to be a way to bring the OfficeVision documents to that PC and FTPed out... and also be able to automate the process. If that can be done, that is an easy route. What do you think? Thanks..

      It sounds as if all you need is a LAN connection. As long as you have an internet connection through the LAN you should be able to configure TCP to take advantage of AS/400 FTP capabilities. Dave

        David, AS400 is on LAN thru the campus, and has internet and FTP capabilites. We are using FTP WITHIN campus as part of campus-related work - didn't even have to set up SSL or DCM. The need now is to do FTP to outside clients for non-campus related work. And the chances are we may be allowed to use their channels. That's why we need to think of some different scenario.

          What about a second network card connected to a DSL modem. Shouldn't it work the same way as if the modem was connected to a PC? If the campus is not going to allow you to use the appropriate ports or FTP outside the Intranet, you are going to have to get a new internet connection of some kind. It could be dail up, I hope DSL, etc. It might depend on your hardware whether you can add a second Network Card. I you are not worried about speed you can alway Dial up to a provider and then FTP.

            Glen, If I understand, you are suggesting a PC with DSL internet connection, and the same PC having another network card connecting to AS400. Then, somehow automate the transfer of document to PC (CAccess or FTP); then automate to take document on arrival on PC to FTP it out thru DSL. Logically sounds good, but is it ok technically? Each network card is going to create its own IP for the PC. Hopefully, someone might explain this further.

This card is connected to, for example, a router/firewall connected to the dsl modem. Then it'd just be a matter of putting in routing information via the CfgTCP menu. bill

                Bill & Glen, Now, that makes me see some light!! Lets take this a little further pl. - Is there a PC involved here? I have DSL on my home PC. Router/modem with firewall was given by phone co.(SBC) with installation SW. It is plugged into the wall phone jack. Can you explain the connectivity with or without the PC pl? Can I use phone co's router/modem? Or buy another one (which?), or use both? - IS there a way to check if i have an open slot for another network card in my AS400? Or, do I need to call the CE? Thanks...

Since I haven't worked with this exact setup, I'll have to wing it (be advised I could be wrong). If you have a DSL modem, and if needed, hook a firewall/router to it - you don't want your 400 attached nakedly to the internet. Connect the 2nd Ethernet card in the 400 to this router. Then enter the appropriate routing information as I described earlier so that the 400 knows that to reach the specified IP address, it has to go through the 2nd card. > - IS there a way to check if i have an open slot for another network > card in my AS400? Or, do I need to call the CE? You should hook up with a hardware reseller. If you are in the Southern California area, I can hook you up with a name. There are a couple sellers that have stores on eBay as well. I believe some of them will work with you, they'll probably just need you to print out a rack config and send it to them. Bill

                    Bill, Thanks very much... I am in Dallas, TX. I will start on this - looks like a good approach. I will-- - contact SBC (ISP in this area)for DSL connection, pricing etc. - look at the rack config, ,and find the network card Which firewall router is suggested? BTW, I met with the IT guy on the campus, and explained him in detail our scenerio. He understands and agrees it would be lot simpler if done over existing set up, and has promised to talk to the powers-who-may be. If they agree, it's fine; but I have to be ready with all the groundwork done if they say nay.

I don't think there are any restrictions as to what would work, so just read up and pick whatever makes sense. I hesitate to suggest one that you might use at home, but it'd likely be a safe choice. I do think that since we're dealing with a business entity picking something more expensive would be in order. bill

                        By 'home dsl modem', I meant to take what SBC would give me with this new DSL connection (not giving up the home modem). I will also check into others.... Thanks for your guidance.

Most homeowners get something like Netlink firewall router for under $100 and that's fine, a business may want to get something better. Bill

                              nshah400, Maybe I read the posts too quickly, but I am confused with the whole PC or second Ethernet card on the AS/400. Here is a simple solution that will work without requiring a PC or second Ethernet network card on the AS400. 1. Get a DSL connection. 2. Get a simple hardware Firewall/router (Linksys, Dlink, NetGear, etc) 3. Connect the network side of the router to the same network the AS/400 is on. 4. Configure the router to use a different IP network scheme. (In other words if your college uses 10.1.xx.xx then use 172.162.xx.xx or whatever suits your taste.) 5. Also configure the router to block all inbound ports (unless you need inbound FTP then create a static route to the AS/400) Now the good part... 6. Now configure the AS/400 Ethernet adapter by adding a NEW static IP address (using your new scheme) to the adapter. And YES the AS/400 can bind multiple IP addresses to the same physical adapter. This is not a new feature, the AS/400 and even Windows NT have done it for years. These are the basic steps and there are some tweaks that need to be done. This way you will be able to FTP directly from the AS/400 via the DSL link without the exposure of having your AS/400 "naked" on the Internet. In addtional other PC's could be added to this "second" network using your existing physical network. They would just need to use the new IP address scheme. I hope this helps.
