I should know more than i do about cisco configs but i admit i don't  . I have a Cisco 1841 Router i need to configure as if it would be a regular router like a Linksys / Dlink / Belkin standard router but no wireless . The setup will be provider , Cisco 1841 then pointed to a Sonic Firewall. There is a DHCP server that will do all the IP addressing behind the firewall . NO ACL needed or anything fancy. We have to use this box because we can't return it. Is there a Cisco Config maker out there or can somone supply me with a simple config that would allow me to do the above? I have a small time line to get this resolved. Sorry if this is not the proper format for questions it my first time

Thanks

let me see if i can help or not:
-------------
1) set up the interface of the 1841 that connecting to the outside network: set up ip address, then enable it;
2) set up the interface of the 1841 that connecting to the firewall: set up ip address, then enable it;
3) set up the default route;
4) done;
-------------

more details and sample configurations can be found in the link below for 1841, just focus on the basis required configurations:
-------------
Configuration: Basic Software Configuration Using the Setup Facility
http://www.cisco.com/en/US/docs/routers/access/1800/1841/software/configuration/guide/b_setup.html
-------------

hope it helps.

ok so when you say interface can it be any .. Sorry for the ignorant question but the WAN i going to be on  conventional router then i have a cat5 cable going to theFast 0/0. So am i setting up fast e 0/0 as a address off the routers ip addreses . In other words the default gateway is 192.168.1.1 do i make the fast e 0/0 on the router 192.168.1.2 255.255.255.0 ?

With default routers will it be like 192.168.1.2 to 192.168.1.1 ?

Regarding the firewall would i set up the fast e0/1 kind of the same way..
Thanks for the quikc response
