Multiple wan PPPoE same gateway

Sun Jul 15, 2018 6:33 pm

Hi,

I try in different way to make that config to work but without succes. I have public IPs just from PPPoE.

I make in exact way like wiki example https://wiki.mikrotik.com/wiki/Manual:L ... bnet_links but without success
I make the internet work from lan but dst-nat no. I want to connect from internet to All IPs from PPPoE but not working.
I try some example but nothing work with DSTNAT

In LOG I see:
Code: Select all
Jul/14/2018 23:16:55 firewall,info firewall: prerouting: in:Local(ether3) out:(unknown 0), src-mac 10:bf:48:4f:3f:11, proto UDP, 192.168.19.252:56740->192.168.19.255:20561, len 50

I want to use dst-nat port forwarding for my servers but I can't do that.

Please can help me with that ?
I do not know what to do anymore

Re: Multiple wan PPPoE same gateway

Sun Jul 15, 2018 8:34 pm

The routing itself (gateway=10.0.0.1%pppoe-outX) is fine but as PPPoE is a point-to-point interface, the interface name alone is actually sufficient as route's gateway (the ip.add.re.ss%interface-name syntax is necessary only for point-to-multipoint interfaces). However, if you want your port-forwarding (dst-nat) to LAN servers to work, you need to assign a connection mark to each connection coming to the 'Tik from the internet to one of the pppoe-outX:

/ip firewall mangle
add chain=prerouting action=mark-connection new-connection-mark=wan1 in-interface=pppoe-out1 passthrough=yes
add chain=prerouting action=mark-connection new-connection-mark=wan2 in-interface=pppoe-out2 passthrough=yes
add chain=prerouting action=mark-connection new-connection-mark=wan3 in-interface=pppoe-out3 passthrough=yes


To route response packets of these connections out via the correct pppoe-outX, you have to translate the connection-marks for packets forwarded from LAN to the internet into routing-marks:

/ip firewall mangle
add chain=prerouting action=mark-routing connection-mark=wan1 in-interface=ether3 new-routing-mark=wan1 passthrough=no
add chain=prerouting action=mark-routing connection-mark=wan2 in-interface=ether3 new-routing-mark=wan2 passthrough=no
add chain=prerouting action=mark-routing connection-mark=wan3 in-interface=ether3 new-routing-mark=wan3 passthrough=no

And you must have the default routes with routing-marks in place:
/ip route
add dst-address=0.0.0.0/0 gateway=pppoe-out1 routing-mark=wan1
add dst-address=0.0.0.0/0 gateway=pppoe-out2 routing-mark=wan2
add dst-address=0.0.0.0/0 gateway=pppoe-out3 routing-mark=wan3

More details here.

Thank you for your support but that already try and not working.

I make to work inside internet connection but when I try to use DSTNAT not working.
Please...do you have an idea ?

If you've tried exactly that and the dstnat (port forwarding of requests coming to WAN to servers on LAN) did not work, the cause must be something else than the multi-wan setup. Recreate the complete configuration which didn't work and post it so that we could check for the other issue.

add distance=1 gateway=10.0.0.1

Hi,

Thank you again ! :)

First I try withot default route /ip route add distance=1 gateway=10.0.0.1 and not working.

If I put /ip route add distance=1 gateway=10.0.0.1 Internet from LAN working but when I try to connect to router from external IP not working.

I don't understand LOG. I see in log and:
Same log for DSTNAT

Re: Multiple wan PPPoE same gateway

Tue Jul 17, 2018 2:06 pm

Have you obfuscated the actual public IP addresses in the configuration but not in the log?

because the log shows:

Jul/17/2018 08:14:01 firewall,info Test: prerouting: in:pppoe-out3 out:(unknown 0), proto TCP (SYN), 62.32.81.83:52837->82.76.164.184:443, len 44
...

But none of the dst-nat rules in configuration matches that destination address:

/ip firewall nat
add action=masquerade chain=srcnat
add action=dst-nat chain=dstnat dst-address=86.116.164.147 dst-port=!8291 protocol=tcp to-addresses=192.168.19.253

Re: Multiple wan PPPoE same gateway

Tue Jul 17, 2018 3:05 pm

OK. The reason why you need the default route without routing-mark: the connections originating from LAN do not get any connection marks, so don't get any routing marks, so need a route with no routing-mark.

But the last /ip firewall mangle rule in your configuration, action=mark-routing chain=prerouting log=yes new-routing-mark=wan3 passthrough=yes src-address=192.168.16.0/22 which you have added probably to solve that has caused packets coming from outside to be routed back out instead of letting them reach the LAN. It doesn't contain in-interface=Local, so even packets which come from (any!) WAN are routing-marked, and there is no route to LAN subnet with a routing mark. So remove this rule and try again.

Thank You for your respone.

I solved but firewall LOG have a lot...lot of error. If you want to store firewall LOG you must have BIIIG HDD
I think in mikrotik can't resolve that (Jul/17/2018 08:14:01 firewall,info Test: prerouting: in:Local out:(unknown 0), src-mac 00:0c:29:02:03:6f, proto TCP (ACK,RST), 192.168.19.253:443->192.168.16.1)

Log events with topics "firewall" are only logged if you have manually configured some rule to log the packet properties when it matches a packet. You are supposed to do so when debugging things and maybe when monitoring some malware attacks, but not routinely. By default, RouterOS logging saves to disk only critical events, and all the rest is stored to memory and the number of events is limited to 1000, oldest ones get overwritten by new ones.

If you want long-term persistent logs, you have to use a syslog server (with a biiig HDD :-) ) and configure Mikrotik to send the log messages to it.

And that particular log message says out: Unknown(0) because the rule which has written that log event is in a prerouting chain, so the packet was not yet routed so its out-interface could not be known.

This is from mikrotik support slow but VERY GOOD SUPPORT!!!
This forum is not Mikrotik support, this is a community (=volunteer) support. The official Mikrotik support deals with bugs and only to a limited extent with configuration assistance like this - compare the amount of topics here (many of them repeatedly dealing with the same typical problems as people have difficulties seeing parallels between their own problem and someone else's problem which is not exactly the same) and the price of the boxes. Normally your authorized distributor of Mikrotik stuff has to be qualified to provide configuration assistance to you, but their margin wouldn't cover a free-of-charge assistance either.

All that is to say that I don't get what kind of speed you would expect :-)

Re: Multiple wan PPPoE same gateway

Hi Sindy and thank you for your support.

I love mikrotik and every time I can do this I recommend mikrotik for my clients but they must adapt to the competition of cheap producers. I'm glad because with your help and mikrotik support I resolved pppoe problem and my clients now is happy. :)
I could give at least 5 suggestions (you laugh at me) that I would be sure mikrotik would increase sales on a certain market segment. It is becoming increasingly difficult to convince a customer that the mikrotik router is better than tplink, dlink,asus etc.. For this reason mikrotik should try to be different from others.


Best Regards,

The reason is simply that pppoe-client, like any other ppp interface, is an L3 interface so packets which come through that interface have neither src-mac address nor dst-mac address.
