I'm setting up DHCP on my new Sophos UTM installation and am looking for some advice before I end up making a mess of things! [LIST=1] Is it safe to assign static AND dynamic IP addresses from the same pool/DHCP definition? When assigning a static IP address I would like an entry to be added automatically to the DNS server. I've done some reading up on this but found it confusing; I think what I read may have applied to earlier versions which look like they may have done it differently. I've been setting up multiple DHCP definitions to allocate from a different range to different types of device (eg PCs vs mobile phones). Now that I've gone down this track I'm not convinced it's workable as the only way Sophos would know which pool to assign from is if it knows the device's MAC address - in which case I would need to have everything assigned statically. I've attached a screenshot to show where I'm setting up the static assignments - not sure if I'm doing it correctly in the right place so would love some advice. [/LIST] Thanks in advance for any help.
