I have a Internet connection from 2 ISP but from one ISP i have just Download and from second ISP i have just Upload and i want to ask u is it possible, in the Router to bisect Download and Upload and my Client to have a Internet with upload and Download…
Can anybody tell me how is it possible to do with Mikrotik
i assume yo have two different ip block from both isp. i.e 192.168.0.0/24 from isp A and 172.16.0.0/24 from isp B. you want upstream traffic via isp A and downstream from isp B. simply, make default routing to isp A (192.168.0.0/24) and use ip 172.16.0.0/24 from isp B for your workstation.
see, your request will flow to isp A and you will have return from isp B. we use same method to combine local isp link for upstream and dvb downstream from satellite provider.
I ask you for This because
I have just Download From Filiago… and Upload From another ISP
and i need to have this combination
This is not the same problem but very similar and should give you a kickstart.

Greetings! YazzY on RouterOS gave me your name and told me to contact
you regarding a problem I’m having. I’ll try to give you all the
details I can about the issue.I have many clients behind the router in 10.0.x.0/24 networks. I have
two outbound connections, SDSL & Cable. We use the Cable as a backup
just in case of problems usually. Well the SDSL provider has decided to
block all outbound port 25 traffic that’s not destined for their SMTP
server. As I don’t want to change over 200 PC’s mail servers, I’m
forced to come up with another solution.What I want to do is send just the SMTP & POP3 traffic out the Cable
connection but leave everything else on the SDSL. I’ve tried src-nat,
but it just refuses to work. I have tried it with a single interface
for both outbound connections and with an interface for each. The
traffic just does not obey my src-nat rules.YazzY has setup this type of thing with his network, but he did it with
two IPs from the same provider on the same line. So I’m not sure it was
identical or not.I’ve tried setting the to-src-address and leaving it blank. I’ve tried
everything I can think of with no luck. The only time I was able to
make it work was with ICMP only. I could traceroute out the alternate
network, but can’t seem to get any TCP traffic to use the alternate
route/gateway.If there’s any way you could help me with this, I’d be very grateful.
If you have any sort of IM or IRC client and would care to chat
real-time, I’d be more than willing to at any time of the day. I look
forward to your reply.
You should have multiple routing tables in your mikrotik and use
flow marks to define which packets will use which table…
First from firewall, you go to Mangle section (well if you are using
winbox) and make a mangle rule select protocol TCP and port 25
and you should select in Action tab the action as Passhtrough and
FlowMark as hmm SMTP, it can be an text really, but this will mark all
your smtp traffic so we can reroute this later. At this moment this
setting wont effect anything until we make the changes in the routing table.
Then you go to IP-> Routes and there you add another table at Tables
tab. Lets name it as Cable and the main default route probably shows the
SDSL? right?
Then you go to Rules table and there you select Flow as SMTP and Table
as as Cable. This will make sure that the SMTP flow will be routed using
the Cable routing table.
You go to Routes tab now and from the dropdown list be sure that the
Cable routing table is selected. (There should be ‘main’ table also).
In the cable routing table, you just put a default route with
destination 0.0.0.0/0 to the gw IP address of your cable router.
This should make all the traffic to port 25 of any host going through
your mikrotik to be forwarded to your cable gateway’s IP address. Then
the gateway would forward it out.
I think its pretty simple way to do stuff. Next if you wanna add more
ports then you can add more mangle rules and mark the traffic as Cable,
all the traffic marked as Cable will use the Cable routing table so they
will go to Cable modem.
i have a downstream using a dvb i am using penta card.is there any dvb card that works on mikrotik cause i am using the penta on a microsoft isa server . thanks a lot for the help
