(if, like me, your whole LAN uses static IP's and they are *not* on that subnet, you can change the IP of the router to match your LAN. my router lives at 192.168.0.1, though I had to flip my mac IP to 192.168.1.3 temporarily, to alter the router's IP, then flip it back. oh the pain! you can also create "virtual" ethernet connexins, serving as many subnets as you need) note: the 205, as supplied by BT comes **insecure** out of the box. I think they imagined the ethernet port would be used only by gamers. BT are a wee bit slow when it comes to catching on to "new" technology like routers. the unit connects itself to the net right at startup, too, so first thing to set is.. Advanced >> Security >> IP Filter set it to "High". Apply, and Save your changes. (the save button appears on all the advanced pages) set the other things up the way you like it, roughly. when you're done with the basic setup, go to.. Advanced >> System >> Backup Config and save the config somewhere. this file is no more than a list of cli (command-line interface) commands for the router. make a copy, and start to hack.. when you're done, load the whole thing back in and your hacks go live! remember to "Save" the setup! (or else "commit" from the command line) to get to the command line, simply telnet into the router. by default it lives at 192.168.1.1 so go into your shell and do.. telnet 192.168.1.1 the account login is the same as the web interface (user: admin password: admin) you can ftp in, too, but although there's lots to see, there's not a lot to do, at least, so far. we'll see. with the right firmware it might do ssh, too. Windows users have telnet too, same command in a DOS shell will work (I think) better still use the excellent Putty http://www.chiark.greenend.org.uk/~sgtatham/putty/ I've only had this thing a day, but info is so scarce online I thought I might chuck up what I've found out so far. I'll probably do a page, with pics and stuff, gonna be a lot of these boxes kicking around pretty soon. I've used # commented lines, but you can't do comments in the console, it's # just to (hopefully) make things clearer. At least, clearer than they were to # me when I started messing with this thing this morning, and getting most of # my clues from chinese web sites! they've had this chipset a while. okAy.... # type any command and then a ? to get help for it, like this.. get ? # you'd then see a list of possible "get" commands, next do.. get ppp ? # for a list of "get ppp" commands, etc. pretty cool. # this works all over in the telnet console. will save you hours! ? # on it's own is the same as help # which is a list of top-level commands. # use the UP key to recall the last command. use this a lot. # after giving help, the cli puts that same command back on the command line # minus the "?", so you can build up long commands one command at a time, # getting help all the way. pretty cool. okay.. # get stats on stuff.. get system get nat stats get ip stats get sntp stats get pfraw stats get ethernet stats get fwl stats get dsl stats curr get user get ipf session # etc.. # set my own domain name.. modify system dname "2C" # create a new user create user name boss passwd mypassword root # NAT everything! create nat rule entry ruleid 1 napt # port forwarding ..
