This ISDN "hub", is it connected only to the back of the NT box? Or does it connect to the same 10baseT hub as the NT box? And precicely what kind of "ISDN hub" is it? I've seen some quite sophisticated ISDN routers in my time, that can handle network address translation for a whole network. However, if it's an ISDN terminal adapter atached to the back of the NT box then it's probably just the ISDN equivalent of a modem. Do other machines (like the last BSD machine in the chain) see the internet? In which case you probably have an ISDN router and you can ignore the NT box. However if it's only the NT box that can see the network you've gor an ISDN Terminal Adapter. In which case you'll need to spend some time geting network address translation working on you NT box. If this is the case.... I'm sorry I've sworn never to darken my soul again dealing with NT :) Assuming its an ISDN router (as the alternative is just too horrible to think about :). Enable the BSD machines to route between their interfaces. Off the top of my head I thing you need to add router_enable="YES" into /etc/rc.conf And then enable Network Address Translation. Personally I compiled IPFilters into my kernel and I use that to do the NAT work. But I suspect you can simply use the natd daemon - type man natd for all the hideous details. Never done it this way myself so I can't advise. The ISDN router /should/ be able to handle address translations for addresses that have already been translated. I would recommend you flatten your network structure a tad. Traffic from/to Win98 machine has to hop through two BSD machines and an ISDN router just to get outside your network. However, I'm assuming you have a definate reason for organising your network this way. > Trevor McMullin wrote: > > I am trying to root throught two networks to the internet any help any > one > can give me will be greatly appreciated > > Network Structure: > > *** Windows98 Network (Peer to Peer) 9 Machines > IP > 192.168.3.55 > > SubNetmask 255.255.255.0 > > *** 10 BaseT Hub > > *** FreeBSD Machine with Two Net Cards > 1st --- IP > 192.168.3.54 > NetMask > 255.255.255.0 > 2nd -- IP > 192.168.2.53 > NetMask > 255.255.255.0 > > *** 10 BaseT Connection > > *** FreeBSD Machine with Two Net Cards > 1st ---IP > 192.168.2.64 > NetMask > 255.255.255.0 > 2nd --IP > 192.168.1.48 > NetMask > 255.255.255.0 > > *** 10 BaseT Hub > > *** Windows Network With NT Server and 3Com ISDN Hub > NT Server IP > 192.168.1.85 > NetMask > 255.255.255.0 > ISDN Hub IP > 192.168.1.1 > NetMask > 255.255.255.0 > > *** Internet IP 206.87.149.17 > > Please email at hybrid@solarwinds.com > Thanks -- TTFN, FNORD Peter McGarvey, Unix Administrator Network Operations Center, Telinco Limited To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
