How to provide access from the Lan network to the WAN through a router?

Question

ASUS

Let's fully describe the situation
There is a provider - from it my Mikrotik router receives wan 10.10.10.10 (for example)
Lan Mikrotik receives 192.168.88.1
There is a web server with billing 192.168.88.254
There are a couple of dozen clients for Mikrotik with authorization via pppoe )
if the client sits behind the nat of the router - he does not have access to the network 88. *
Maybe on Mikrotik you can configure something to let them in?

Answer 1

kolenchits86 : route add -net 192.168.88.0/24 gw
192.168.1.1

Answer 2

no way, they already have access there from the wan address of the router

Answer 4

in the properties of the lan-interface, which is master, did you try to specify proxy-arp in the ARP field?

Answer 5

I have a lot of clients and it’s no longer possible to go to them to set up the possibilities, you can’t prescribe anything in Mikrotik itself that will help solve this problem:?

Answer 6

On Mikrotik, in IP => Firewall => NAT, you need to create a rule:
- chain = dstnat
- src address = network from which addresses are assigned to pppoe clients
- dst address = Mikrotik address in pppoe tunnels
- protocol = tcp
- dst port = 8001 (for example)
- action = dst-nat
- destination = billing ip-address and port
Then pppoe-clients will be able to enter billing via http://ip-address-mikrotika-in-pppoe:8001/
