Why dont you just copy and past this config on the new router?

[balaji.bandi]

#as suggested you can do copy and paste on a new device or use TFTP to copy the config?

do you see any challenges?

[Leo Laohoo]

What WAN speed is this router going to be hooked up to?  

[Richard Burts]

I am a bit puzzled about the original post. If the posted config was not for an 1841, then what was it for? Other than possible mismatch in interface naming/numbering what about this config does not work on 1841?

This config is specific about addressing of the outside interface and the static default route. Obviously these would need to change if the new implementation does not use the same Internet provider addressing.

This config uses a pretty large address space for inside addressing with an interesting set of excluded addresses. Is this part of the issue of implementing on 1841?

The original post implies that they have attempted to use this config for an 1841 but it did not work. Perhaps they can be a bit more specific about what parts did not work?

It didn't work because they plugged a tiny 1800 router to a 100 Mbps link.  Combine that with "default" DRAM size and throw every-man-and-his-friend NAT, something's gotta give.

It's 2022 now, why not buy a Cisco 1921?
