But if it fits on the Buffalo, it should also fit on the WRT54G. I do not remember if this firmware was a trx file or a bin file. My Buffalo WHR-G54S has 'Tomato Firmware 121 ND VPN' installed on it, and that supports VPN. Some of the K26 firmware might work on this old router, but which version includes VPN and would fit? That's not clear to me by looking at the available downloads.

It appears that the Tomato firmware I need only comes as a trx file (the old K24 stuff). My firmware choices are limited, due to the small flash size of this old router. But I need VPN for this router now, and the DD-WRT firmware currently on it does not support that. Why I installed DD-WRT on this particular 'G' model is a mystery to me. Or was installing DD-WRT years ago a fatal mistake? All my other old routers from the same era as this WRT54G have Tomato on them (a Linksys WRT54GL and a Buffalo WHR-G54S). My question is really 'How do I get this firmware onto my router'? I don't really care why DD-WRT doesn't allow the upgrade, I simply want to know how to do the upgrade.
