Hi Nick, This could well be a basic networking issue as you stated...
Personally, if you have a single interface AstLinux box I would generally recommend using VLAN's for the phones behind AstLinux so the AstLinux DHCP server is used to configure the IP Phones. If you do not have a managed switch that supports VLAN's, or are not comfortable with VLAN's, then we have to go back to the basics. But with VLAN's your AstLinux box with one interface can be viewed as a "router-on-a-stick" where the untagged packets (ex. eth0) act as the external interface connected to your private network and your phones can be configured as an internal interface on AstLinux using a VLAN (ex. eth0.20). The phones often use a PoE switch, separate from your main switch, which can manage all the internal VLAN interfaces AstLinux can provide. You may also want a data VLAN (ex. eth0.10). Each VLAN interface would be a unique private network. Note: If you have not used VLAN's before, you don't have to use them, and getting your head around using VLAN's can be tricky at first. Can you provide your basic network layout, ASCII drawings are fine. Showing the private IP address can be helpful as well. Given the single interface, my hunch is the AstLinux external interface is on the same private subnet as your IP phones, and the DHCP server is not AstLinux but rather some upstream router and your problems begin there. Tip: rather than using wireshark, "tcpdump" https://danielmiessler.com/study/tcpdump/ is available on AstLinux, a worthy skill to have.
