    I am using a WRT54GL with Tomato 1.23

    When backing up my configuration, does it also save the NVram values?

    When restoring my configuration to a new router (also running Tomato 1.23), it wont let me. Any way around that?

    I would suggest to avoid problems to always start from anew if you erased your nvram.

    U can't use a configuration that is for a particular router, to another router, due to the differences in the MAC address. For another router, it's always recommended to do a thorough NVRAM reset and reconfigure.

    I can't imagine what else there is to save.

    How won't it let you?

    I can imagine that it might not be happy about copying immutable data such as the source router's MAC address.

    If that is the reason, what you can do is examine an "empty" configuration for immutable data. Then, before the cloning, give the immutable data the proper values.

    (On a Unix system you can use gunzip to uncompress the file. Then use your favourite (nonmangling)* editor to adjust it for the new router. Then gzip it. Then restore to the new router.)

    (* -- avoid adding NL's or CR's.)

    If this sounds too complicated to you, you should listen to the voices that say "do it all over again, again, ...".

    BTW, to correct some persistent disinformation to the contrary:
