I have an RB750 running RouterOS 4.6 and I have a question regarding Masquerading a couple of networks...
My current setup is as follows:
I have a PPPoE connection to my ISP with a public address as my end point (illustrated as 253.12.13.14/32 in my example).
There is a set of public addresses routed via the MikroTik (the 252.1.2.0/28 network) and two separate private office networks.
The public network routes correctly to the internet and the two private networks can route to one another, and can access the internet via NAT, masquerading behind the PPPoE endpoint address.
Simply for accountability purposes, instead of the two networks emerging as the PPPoE endpoint address, I'd like to assign an address within the 252.1.2.0/28 for each of the masquerade sessions, however I can't find a way to do this as the masquerade instructions appear to require an out-interface:
/ip firewall nat add action=masquerade chain=srcnat disabled=no out-interface=ISPpppoe src-address=172.17.72.0/24
/ip firewall nat add action=masquerade chain=srcnat disabled=no out-interface=ISPpppoe src-address=172.17.73.0/24
If anyone has any idea as to how to approach this, i'd be most grateful if they could share them
