Configure cisco 801 router 2

[mtoto]

Hi!<br>
I need to configure a 801 router to access at the same time to Internet and a remote office .<br>
How can I do this?<br>
<br>
Thanks<br>

I am not that familiar with the 800 series, but it looks to me like you can connect either to the Internet or to your remote office, but not both, with a Cisco 801. It only has a single ISDN port. and a single Ethernet port for your LAN connection. You would be better served with a 1603 [ISDN S/T] or 1604 [ISDN U], either of which will support an additional WIC to connect to a remote office via leased 56K or T1 circuit [depending on WIC chosen] There are scads of information about these routers at Cisco's site. Good Luck<br>

On a 2B+D BRI why couldn't he/she use one B channel for Internet connectivity and the other for inter-office data?<br>
<br>
I haven't tried this on an 800 series router either, but I suspect the configuration wouldn't be all that complicated.<br>
<br>
There isn't enough information in the original post to give a complete configuration (like do you need traffic from both of your locations to share the one Internet connection or just from the main site, do you have IP space assigned from your ISP for your local machines or do you need to do NAT, do you need to get an address assigned to your router dynamically from your ISP or did they give you a fixed address, do you have special security needs beyond simple access-lists, etc).<br>
<br>
I don't know your background, so rather than try to give you a config that I THINK will work but might need some tweaking I'd probably suggest you try using ConfigMaker from Cisco. It should have come on a CD with your router. If you bought the router used and don't have the CD you should be able to download a copy from<br>

<br>
ConfigMaker is a graphical configuration tool that will ask you questions and, I hope, produce the configuration that you are looking for. After all, Cisco's sales documentation on their web site says that the 800 series was intended for exactly what you are asking.<br>
<br>
If you would prefer to use the command line interface and need help with the config post another message to this thread with more details about what you want to do and I'll see what I can come up with.<br>
<br>
Good Luck.

Good Thanks to Gonzo1 and Salvalinus for yous replies.<br>
The goal is to use one B channel for Internet connectivity and the other to connect offices.<br>
Configuration provided by Configmaker is no longer consistent and the commands are not always invalid when changing configuration options.<br>
I'll try to describe what I must do.<br>
1. use on B channel to connect the other (remote) office without particular authentication<br>
2. use the second B channel connect my local office (only) to Internet with chap authentication.<br>
3. No device in my local office has an pre fixed IP address. So I need to get an address assigned to the router dynamically from my ISP.<br>
4. No security is required.<br>
<br>
I hope Salvalinus would help me to acheive my goal.<br>
