Re: RE: strange nat problem .. memory allocation

You would probably see same behaviour on a real router.
The more features you use, the more memory you need. Every entry of every
routing protocol, every additional feature, everything requires memory. For
the image and box you are running 128M is very minimum.

Allocate it 256MB in the settings, and you will see the problems go away.

This is why 7201 ships with 1G memory standard and 2G memory as an option.
Features need memory.
