Hi primavat,
no, proxy-arp is not going to work in this case, since your hosts will not do arp requests for destinations that are outside their subnet, they will just forward these packets to the default gateway.
So you have several options:
- define static routes on your hosts;
- on the pix, route the new address space to the new router. I'm not sure this will work with a pix, since it means it will route traffic out the same interface as it came in;
You could do the reverse though: make the router the default gateway for all hosts, and add a static default route on it towards the pix.
- move the existing hosts "behind" the router as well, so there are no hosts on the segment connecting the router and the pix;
