Hi Friends,

Please refer a network setup attached.I want to have 2 Public IP address for firewall ,1 for active and 1 for standby and 3 to 4 Public IP address for my servers , if my Service provider gives me a /29 address block , will that meet my requirement Please advice.

thanks in advance.



There is no attachment but from your description you should be fine as long as you do not want to assign the public IPs directly to your servers which i assume would be on a DMZ. If your servers are using private RFC 1918 addressing and you are then Natting them on the firewall eg.

static (dmz,outside) netmask

then you should be fine.
