DHCP lang ba talaga ang kay WAN? Pa enlighten naman sa OO at HINDE medyo confusing.
WAN connection accepts PPPoE/A, Static and Dynamic, WAN interface can also authenticates via Radius server but almost no one uses Radius as their mode of authentication on WAN interface except on certain FTTH connection of AT&T in USA.
But since nasa pinas lang naman usuall its just PPPoE, Static of Dynamic.
PLDT depending on the plan, residential plans uses DHCP, Business Plans uses PPPoE with static IP
Globe uses PPPoE connection for residential plans and static IP for business plans
Protip for globe connection: if youre globe modem is in bridge mode and you let pfsense to authenticate to their PPP server make sure to check the Block Bogons network option, since for some reason, Globe randomly leases 10.xx IP which you will have no internet connection at all, checking the block bogons network will fix this 10.xx IP leases, pfsense will automatically reconnects to globe until it gets a valid IP address 100.xx for globe residential under cgnat.
Pwede bang ilagay ko dito public IP sa WAN1 & WAN2?
you can if your ISP is leasing Public IP via DHCP connection, else contact your ISP to avail a static IP instead since thats the only option you will get a public routable IP address.
sino po gumagamit ng snort dito?
Tama ba na sa LAN interface ko lang siya ilagay?
it depends, for me I usually set it on exit nodes which is the wan interface since I have gazillions of vlans if I assign them on each network, in your setup since iisa lang naman yung LAN interface mo and no VLANs either, just set it to LAN.
