Hi,

I have a network 192.168.1.0 /25.  This network's use has ballooned and I only have 4 addresses left to give out.  I would like to change it to 192.168.1.0 /23 (to go from 126 addresses to 510).  Here are my steps :

1. Change the firewall interfaces for 192.168.1.0 to the new subnet (as the firewall also does the routing between networks).
2. Change the servers subnet masks from /25 to /23 as time permits (during this time all /25 hosts should be able to communicate without issue correct ?  They will have to change to /23 subnet inorder to communicate with new nodes in the new parts of this subnet correct ?).
3. I do not run any routing protocols like RIP or OSPF (everything is static), so no biggie there.

Am I oversimplifying things ?  Is there anything I am missing ?

Thanks
