Hi there, I have 3 cisco 1841 routers and I am trying to setup 'ip nat inside' on a serial interface and I keep getting a memory error.
Ive been stuck for two days, Ive tried it on one of the other routers and its fine, so I swapped the flash card over to this one and its doing the same thing.
Any help would be awesome please, Ive pasted the output below.
Many thanks
Robin

Hi,
The version you have installed needs 128MB of DRAM, and you have only 96MB.

No he doesn't. The sum of 96256 and 34816 means the router has enough DRAM.
