NAT 1:1 over 2 gateways

RouterOS General

Hi there,

need to forward IP with all ports to the customer.
I have next scenario:
From provider IP stack is pointed(routed) to external IP
internet->eth0(inet)-main-eth1(lan)->switch->eth0-pppoe(gateway)eth1->customer(pppoe)-static.1.1.1.1

How do I see it
main:
add ip address 10.10.10.10(that will be routed)
on eth0 and eth1 proxy-arp enable

/ip firewall nat add chain=dstnat dst-address=10.10.10.10
action=netmap to-addresses=eth0_IP_pppoe

/ip firewall nat add chain=srcnat src-address=eth0_IP_pppoe
action=netmap to-addresses=10.10.10.10

pppoe(gateway) eth0 - proxy arp enable
eth0 → add ip address 10.10.10.10

/ip firewall nat add chain=dstnat dst-address=10.10.10.10
action=netmap to-addresses=customer(pppoe)-static.1.1.1.1

/ip firewall nat add chain=srcnat src-address=eth0_IP_pppoe
action=netmap to-addresses=customer(pppoe)-static.1.1.1.1

How does it like? :slight_smile:
Thinking to jump off to zeroshell all gateways(main), like it more.. more flexible @my point of view, pppoe-d could stay on tik :slight_smile:

Hello
What you want to say it. whether it is something you would like advice or help from here?

just checking configuration logic :slight_smile:

Sorry but previous post means that the logic is not understood (and I agree with it). Could you describe your design task?

we receive external IP from ISP. We need to make 1:1 translation over 2 routeros gateways(first one with dhcp-server) second one with pppoe (end user authentication with pppoe)…
