PPPoE Client on RB750G
Thanks to Hilton Travis of Quark Group for the following info!
For those who want to modify the default config and place the RB750G behind an ADSL modem in bridge mode (instead of the default config where the RB750G is a router behind a router) rather than wipe the default config and configure the RB750G from scratch:
1. Disable DHCP Client on the RB750G
a. WinBox, IP, DHCP Client, ether1-gateway, disable
2. Assign a static IP to the ether-1 interface on the same network the ADSL Modem’s LAN is using (assuming ADSL Modem is 192.168.1.1)
a. WinBox, IP, Adresses, ether1-gateway
i. Address = 192.168.1.2
ii. Network = 192.168.1.0
iii. Broadcast = 192.168.1.255
3. Add a PPPoE client interface to authenticate to your ADSL provider
a. PPP, Interface, Add, PPPoE Client
i. Tab = General
ii. Name = pppoe-out1
iii. Max MTU = 1492 (default is 1480 for some reason)
iv. Max MRU = 1492 (default is 1480 for some reason)
v. Interfaces = ether1-gateway
vi. Tab = Dial Out
vii. User = ADSLUsername
viii. Password = ADSLPassword
ix. Profile = default
x. Add Default Route = Checked
xi. Allow = pap (the rest, depending on your ISP, can be unchecked)
4. Modify the default NAT Masquerading rule to send traffic out the PPPoE interface instead of ether1-gateway
a. WinBox, IP, Firewall, NAT, default configuration masquerade
i. Out. Interface = pppoe-out1
5. Add a static route so you can access your ADSL Modem’s web interface from the LAN (assuming ADSL Modem is 192.168.1.1)
a. WinBox, IP, Routes, Add
i. Dst. Address = 192.168.1.1
ii. Gateway = ether1-gateway
