Dear Sir! We have a FreeBSD box which will be connected via RS232 (serial) interface to an existing BSD host. We are attempting to add a SMALL network of ethernet connected machines to the FreeBSD host. These machines will require access to the internet, but I really don't want to allocate addresses to them from our (diminishing) IP allocation. I've heard from various sources that programs like wingate for windoze-95 and some similar products allow additional PCs to use IPs in the reserved 192.168.x.x range, and transparently gate them through to the net. I'm not sure how (if) this can be achieved with FreeBSD, but hope you can help us. To date, we have managed to connect the FreeBSD machine to our BSDI host via RS232, and have nameservice etc all operating happily. We can alternatively, connect via ethernet and also things work fine. What we want to do, but have been unable to work out *exactly how* is to use a *different* address block (192.168.x.x) on the ETHERNET (ep0) interface and allow boxes attached to that ethernet segment to access the internet via the RS232 link. There is a *slight* complication in that the machine will also have a couple of indial lines (modems). These should also operate in a similar manner to the locally attached Ethernet machines. Don has previously set up ppp on one test port, and dialed in sucessfully, and established a ppp connection. The FreeBSD box allocated him an address of 192.168.x.x (correctly) but would then not allow him to access anything apart from the local machine (by telnet). I think this is because of netmask settings, but have not confirmed it yet. Netmask settings should not be a problem however, as in a working configuration, the BSD host should KNOW that the required address is "out that port" and route it accordingly. After all, that's what routers do. What are we doing wrong? or not done that we should have? (is there a FAQ on all this somewhere? or a set of magic config files?) Best regards, Ross Wheeler
