I need some help from a mikrotik pro

Right heres the deal just signed up for axxess dsl combo 4mbps with static ip.

Was using my mirokitik in pppoe client mode and the billion dsl router in full bridged mode just to terminate ppoe connection.

Now i want to use the billion as the pppoe terminater so to speak and as the l2tp tunnel for the static IP as stupidly enough axxess dont support l2tp through a mikrotik and yes i have tried everything.

my current network setup

mikrotik ip: 192.168.1.1/24
billion ip: 10.0.0.1/24

assigned ip to gateway 1 port on mikrotik: 10.0.0.220/24
ports 3-5 are the lan slaves with lan ip being : 192.168.1.1/24

Ive tried setting the billion to port forward to the mikrotik because i want my billion to handle all of the nat / firewalling / proxy etc....... I have tried and tried and to no resolution and im pulling my hair out trying to get this working.

Please can somebody help.
 
This is a double nat setup.

You can try check the following on the mikrotik:
- add route to 0.0.0.0/0 with gateway 10.0.0.1
- add srcnat masquerade for out interface gateway 1 port

If it's still not working try pinpoint the issue:
from winbox, use the ping tool to see if billion ip is reachable, then try a public ip like 8.8.8.8
then try the same from your pc.

For incoming requests: on the billion you will need to port forward to the mikrotik ip 10.0.0.220, you will then need to add dstnat rules on the mikrotik to your internal 192.168.1.? server you want to expose to the net. If forwarding everything to the mikrotik remember to add deny rules and lock down local services (ip -> services)


Hope that helps you.
 
Guys I have a Tenda d309r router with MT but I do not have the web interface password? I have tried the typical ones (blank, admin, isp's name). Sometimes when I boot it I get the Tenda interface, is this usual?
 
Nope ISp must be a security crackpot Changing router passwords pfft. Managed to get into the tenda interface with some fidgeting
 
Grassmuis I know well actually it does support the L2TP just not the crappy one there using ofc, if u read my post I stated that i was using a billion to achiev the the L2TP dialup therfor allowing the billion to get the IP address, Problem im having is forwarding all the traffic from the billion to the mikrotik.. for some odd reason it just refuses. got the internet working beatuifully throught it just the port forwards are where I am getting stuck, I forwarded everything from my billion 1-65535 tcp/udp to 10.0.0.222 my new mikrotik IP address and still nudda.
 
That should work but you need to setup the nat via telnet, doen not work on the web interface for some reason.

telnet 192.168.1.254
Trying 192.168.1.254...
Connected to 192.168.1.254.
Escape character is '^]'.
Login: admin <- same login as your webinterface
Password: *****
Login successful.
admin> nat status <- to get your l2tp interface name
NAT enabled on:
ID | Name | Interface | Type
------------------------------------------
1 | nat1 | ipwan | internal
2 | @nat_pppdevice16 | @ip_pppdevice16 | internal
------------------------------------------
admin> nat add globalpool test1 @ip_pppdevice16 internal 105.208.0.9 endaddress 105.208.0.9 <- make the billion aware of that ip, the "test1" can be any name
admin> nat add resvmap map1 interfacename @ip_pppdevice16 192.168.1.100 tcp 80 80 80 80 <- this is the actual port forwarding put into place specify to what ip address , protocol, (start port, end port) for the static ip, (start port, end port) for internal server
admin> system config save
 
You also need to downgrade the firmware to ver 6, had some problems with the nat on the latest firmware
