SUbnet routed through subnet

TomMorgan

Sophos SG 230 / UTM 9 (latest)

We recently switched to fiber service. Our ISP did something that I haven't experienced. That is routing a /29 through a /30:

/30
Network: xx.xx.1.20  (primary external IP
Gateway: xx.xx.1.21
Useable: xx.xx.1.22
Broadcast: xx.xx.1.23

/29
Network: xx.xx.163.56
Gateway: xx.xx.163.57
Useable: xx.xx.163.58 thru 62
Broadcast: xx.xx.163.63

xx.xx.163.56 thru .63 creates 24,000 dropped destination hosts log entries daily

The /29 are supposed to be our available static IP's so:

1) How do I setup the statics I need?

2) How do stop the log entries for those statics I do not use?

 

Thanks,

Tom

    Network: xx.xx.163.56
    Gateway: xx.xx.163.57
    Useable: xx.xx.163.58 thru 62
    Broadcast: xx.xx.163.63

    I guess my question could have been clearer, Tom.  Is xx.xx.163.57 the ISP's gateway or is this your plan for a DMZ using public IPs?  If it's indeed the same ISP for both subnets, I would expect the latter.

    Yes Bob, it's the same ISP for both subnets. They stated that they routed the /29 through the /30 and I would use the IPs from the /29 for my statics. Previously (using a coax system) we had one /29 network with 5 statics, one of which we used as a public IP. While I wasn't thinking in terms of DMZ for this new setup, I do want separate networks.

    Thanks
