1 ISP mutiple IP blocks PPPOE

RouterOS Beginner Basics

Hi,

I have had my Rb 1100 for a few months now. I have been playing with it and really like it. Most things I have gotten working others not.

I am stuck on this, so I seek advice and help, I am guessing its easy but I no not how to make it work.

I have a /28 and a /25 from my service provider.

I currently have the /28 working. I have a hotspot running on NATed address. I have my internal network running on another NATed network and I have a PPPOE server running passing out public ip addresses to the end users on a wireless network (not the hotspot)

Now I want to add in the /25 pool for the use of the PPPOE users. I can get it to assign the IP addresses no problem but no internet access.

Port 1 - wan IP xxx.190.84.226/28
Port 2 - internal lan IP 10.11.0.1/24
Port 3 - Hotspot 10.11.1.1./24
Port 4 - PPPOE (network behind it for wireless equipment is 10.11.20.1/24

I have proxy-arp enabled on Port 1 and port 4

My gateway is 0.0.0.0/0 xxx.190.84.225

I want to add my xxx.190.85.0/25 block for use by PPPOE I was told the gateway for this block is xxx.190.85.1.

I have tried OSPF examples, didn’t work. I have read though the wiki many times, and can not find exactly what I want.

I get the feeling I am missing something very simple.

Any help would be grateful.

First try to get your provider to set this up for you properly. Request that they route you the /25 via the /28 you already have. Right now it’s not routed or they wouldn’t be giving you an IP address as a gateway to use for that network. Once you have the IP space routed to you via the existing link you can simply assign the entire /25 to an IP pool to use for PPPoE. That’s clean, simple, and the far preferred way of doing things.

If they don’t want to route the IP space to you - and I cannot iterate enough how much you want to be using that option: if they say no, escalate, get with the sales team, offer to pay more - then you can configure .2 on your existing WAN interface, turn on proxy ARP (yuck, yuck), and assign the rest of the IPs other than .1 and .2 to an IP pool to use for PPPoE. You will then have to install a route with a routing mark for quad zeroes via the .1 address of the /25, and use IP firewall mangle rules to mark all packets from that /25 to use the routing mark route.
