Quick Question about Network Block

Should be easy answer,  I just want to confirm if I am doing this right as I've started a new UTM from scratch and couldn't transfer over my definitions due to hardware change.

I regularly get ranges of IPs which although coming from specific countries, evade country filtering and rotate IPs to brute force.  I have a firewall rule and an underlying network definition that I use called known attackers to block at the firewall layer; I also use this definition in NAT and email protection.  Instead of entering individual IPs I normally create a subsequent definition in known attackers with the type network and enter the IPs in the style of 192.168.1.0 and subnetmask 255.255.255.0 with the final octet a zero to denote the entire range.  Is this correct, or should I be using the range definition and setting 192.168.1.1 - 192.168.1.255?

Thanks,

Jared

  • first: you should be able to transfer your config to new hardware. Possible you have to reorder the interfaces afterwards. You need a new license if hardware type changes ... afterwards too.

    you may use a range definition or a subnet definition. booth should work.

  • Thanks for this feedback.  Normally I would have done as you suggest, but unfortunately the config backups from my home made system applied to dual SG210s caused some very weird DB failures and inability to apply NAT or firewall rules.  I decided the best approach was to start from scratch.
