Hello - hopefully a straight forward one....
We have several relay sites that have wireless access points with CPE connected.
Some of the CPE (but not all) want a static IP.
I am doing this with PPPoE and running PPPoE at each relay rather than centrally (I have reasons for doing it like this).
I have a /25 public IP range that I wish to use as sparingly as possible. As some sites might only need 1 or 2 CPE with public IPs, how is best to achieve this without wasting public IPs on subnet's that are larger than what I need?
At the moment, I give clients a static IP per ppp secret rather than using a pool as that works well for a per user basis of public IPs.
/ppp secret add local-address=1XX.XXX.XXX.112 name=user1@relay1 password=somepassword \
/interface pppoe-server server
add default-profile=My-Standard disabled=no interface=My-PPPoE max-mru=\
1492 max-mtu=1492 mrru=1600 service-name=MyService
The main bit I'm struggling with is the use of the local-address . I can give remote address (what the client gets) as a /32 and that's efficient. If each PPPoE needs a local-address, that's fine, I just want confirmation that it is the case or if there's a better way of doing things.
Do I need to use a local-address on each site so there is some reference on the router to the public IP or can I drop this and just a /32 on the PPPoE remote address and leave it at that?
Any points would be appreciated.
