I have a RB-1100AHx2, which is effectively 2 x Routerboards + 3 extra ports, 2 ports, 11 and 12 can be physically switched together, It is a live unit with a lot of users attached via the wireless network, the 6 wireless networks all come together at this unit.
All but two are natted on to one subnet and the wireless units which act as routers, receive their local IP’s via DHCP, the two that are on their own subnets and on their own ports are still natted from the same WAN IP.
Now that I have the public IP Ranges, I am converting all the wireless units from nat routers to bridges and setting up the premises ( Customers ) routers to pppoe, however because I can not do every customer at once ( some require site visit’s ), I have set up pppoe to use different local ranges as well, these are srcnat from the same WAN IP. the wireless unit will stay on a different local subnet.
I have just worked out that I can have each subnet natted from different WAN IP’s and have tested it on the bench using a RB750, however it is still using NAT.
<What I would like to do is route the pppoe clients as they are converted from DHCP on to their public IP’s but keep those units that are still using DHCP and SRCNAT to continue using NAT, anybody know if this can be done and if so how?>.
I know I can still achieve the end result it the following way:-
Convert all the units to pppoe then switch the pppoe server to issue public IP’s and remove the NAT, this is what I have started doing.
