Hi, i’m struggeling with a configuration any help is appriciated.
Mikrotik is connected via PPPoE to my service provider.
I’m allowed to use a public /29 subnet.
when i configure pppoe client on mikrotik i dynamicaly gets one IP address out of this /29 range
I want to use 5 of the /29 public adresses to devices behind the mikrotik
How do I get the 5 other devicess linked to this pppoe link ?
I got a cisco example config from my service provider unfortunalty i’m not a cisco guy
The cisco config is not really helpful.
Please check your PPPoE connection status if your local address gets a /29 subnet mask.
If yes, 1:1 NAT could be a quick solution - translate a private address of a host to a public address from the /29 subnet.
There are probably better solutions, but I can’t think of any so quickly.
Either way - your ISP is a bit weird. I would understand if they gave you one PPPoE connection address and route the /29 subnet behind it…
Just configure the public address with a /29 mask on another interface (Ethernet). The router will have the same IP address on two interfaces but will work. Causes issues with multicast but otherwise isn’t normally a problem.
For Corporate Internet KPN customer does not get one IP address as usual for internet services
for individuals, but a block of IP addresses (8, 16, 32, etc. IP addresses). In order during the
build-up of the PPP session, an IP block to the customer from the customer router sharing a router should
to do special request. This is the so-called “netmask IPCP request”, the implementation of this
feature can be different for each manufacturer. The client router is required to request the
netmask to have working for the Cisco implementation of the Access Router side. This is not to
say that the client router must be a Cisco router, but it must be compatible with the
Cisco implementation of the IPCP netmask request.
