Virtual IP Config for AT&T Static Block:

IP Address Interface Type Notes
XXX.XXX.130.201/32 WAN IP Alias
XXX.XXX.130.202/32 WAN IP Alias
XXX.XXX.130.203/32 WAN IP Alias
XXX.XXX.130.204/32 WAN IP Alias
XXX.XXX.130.205/32 WAN IP Alias


I've seen two conflicting posts regarding 32 vs 29 on this configuration? Your thoughts please & thank you.

/29 for the first address, /32 for all additional aliases.

Thanks, Patrick.

Those are actually the five I can use. there's a sixth I didn't list (xxx.xxx.130.206) which is the AT&Tgateway, i have that one set up as a Gateway, but I'm unable to put a /29 CIDR in "Gateway."

Should I also list the Gateway as a Virtual IP with /29?

The gateway goes in System > Gateways as a single IP address without a prefix length, not in virtual IPs.

To clarify: your first address goes in the Interface configuration with a /29 length. The remaining 4 addresses go in virtual IPs with /32.

OK, great, Ill make that adjustment now.

I attached some photos of the configuration, I'm following. My only concern is the NAT 1:1 that was advised.
