Routing Traffic from one network to other

RouterOS Forwarding Protocols

Hi, I have the next scenario:

Cloud PBX (159.90.90.90) —Mikrotik (WAN ETH1: 190.90.90.92/ETH2:192.168.6.1/ETH3:10.90.90.92)----ISP(10.90.90.91)-----SIP Proxy(10.0.0.1)
Static route:

[admin@MikroTik] > ip route print 
Flags: X - disabled, A - active, D - dynamic, 
C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, 
B - blackhole, U - unreachable, P - prohibit 
 #      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 0 A S  0.0.0.0/0                          190.90.90.91            1
 3 A S  10.0.0.1/32                    10.90.90.91             1
 4 ADC  10.90.90.90/30   10.90.90.92   bridge2                   0
 5 ADC  190.90.90.90/29  190.90.90.92  ether1                    0
10 ADC  192.168.6.0/24    192.168.6.1    bridge1                   0

I need to route traffic comming from PBX to sip proxy and vicebersa.

Do you have any idea how to do it?

I’ve tried some dst-nat, but it didn’t work.

Thanks in advance.

David.

Hi! I think that you’ll need some routes between your devices, can you upload a simple diagram of your network? it may be easiest to understand your problem.

Hi @sri2007,

Thanks for your interest.

Here is a network topology.

And I must add that bridge 1 is ether2, 4 and 5 and bridge 2 is ether3.

I hope now is clear the situation.

Thanks in advance.

Add route on Mikrotik:
10.10.10.0/24 Gateway: 10.90.90.91

Sorry, wrong interpretation… forget it :slight_smile:

Is the SIP proxy network under your control?

Hi WeWiNet,

Not, only the Cloud PBX and Mikrotik is under our control, the ISP router and proxy are out of our control.

By the way the route 10.10.10.0/24 Gateway: 10.90.90.91 exists.

What we need is to be able to route SIP traffic from the ISP to the Cloud PBX and from Cloud PBX be able to reach ISP SIP proxy.

Thanks for your time.

David
