So i have a pool of IPs that I use for PPPoE connections. Lets say 192.168.100.1-192.168.100.200 for example.

Most of the IPs are in use from that pool.

I was trying to setup a static connection (/30) and due to some out of date documentation, I tried to put that static subnet in the router within the pools addresses. FOr the example I used 192.168.100.5/30 and 192.168.100.9/30. I quickly realized that I was not ablt to use those subnets there so I removed them and found another location for the IP addresses.


My problem start in that now, what was the network IDs of those subnet are now broken. Even if the PPPoE pulls from the pool and uses those IPs I can pass no traffic to them.Using the subnets in the example 192.168.100.4 and 192.168.100.8 are now unusable. All of the other IPs from those two temporary subnets (usable IPs and broadcast) are still working.

I have no visible ARP entries for those IPs and it does not matter what device I have that recieves those addresses, they simple will not comunicate. I cannot ping to those IPs and I cannot push any traffic.

Any ideas?
Thanks
