PPoE client / DSL client: All four models can be used as a PPoE client: Solve limitations/restrictions of DSL modems, simplify, & save IPs
“ Reduce number of public IP addresses required by 1 or 2.
“ Assign your 1 public/static IP to this router rather than your DSL router
“ Enable RDP access behind DSL modems that block RDP (Terminal Services / RDC), such as Qwest ActionTek (PK5000 & others)
“Put your ActionTek DSL modem into Transparent Bridging mode, and the MikroTik RouterBoard can take over all routing & firewall functions from the DSL modem. This greatly simplifies your network topology – you won’t have to configure your DSL router or having any troubleshooting problems with it.
