Hi

by Ros manual if you create pppoe server is asking to start proxy arp in WAN card

How is possible to create pppoe server without using proxy-arp or bridge between network interfaces
Some kind of static rules

Thanks

*My windows PPPoE client obtains IP address and default gateway from the MikroTik PPPoE server, but it cannot ping beyond the PPPoE server and use the Internet

*PPPoE server is not bridging the clients. Configure masquerading for the PPPoE client addresses, or make sure you have proper routing for the address space used by the clients, or you enable Proxy-ARP on the Ethernet interface

I use public IPs for client so i don’t need masquerading.


If any other manual is available will be very happy to look in to

things become a bit clearer.

is your address space bridged or routed to you by your ISP?

to explain is better to draw a small map (i had to make like this)

1 ISP provider router (has pubic IPs clasess here) → cisco switch → 2 bridged shaper ; 2 PPPoE server → 3 Clinets with static IP ; 3 Clienets on PPPoE




I dont have access on ISP router who has all IP ranges inside (about 7 ranges /24 )
I just bridge clients to that router

Hope this make more clear for you

if you must bridge clients to ISP’s router - then yes, you should enable Proxy-ARP on WAN interface. or you may ask your ISP to route those subnets to some of the fake addresses on your router
