My ISP (Zen) has given me a block of 8 ip's but i need to connect via PPPoE. The ASA 5505 only allows me to put the static in as a /32 instead of a /29.
Has anybody configured an ASA with a block of 8 ip's using PPPoE before?

HI Louis,
That is the default behaviour of PPPoE. Even you configure that as /29 it will take it as /32 only. No worries....
Excerpt from Cisco Doc:
Problem
When you use the IP address x.x.x.x 255.255.255.240 pppoe setroute command, the IP address is assigned correctly, but the subnet mask appears as /32 although it is specified in the command as /28. Why does this happen?
Solution
This is the correct behavior. The the subnet mask is irrelevant in the case of the PPPoe interface; the ASA will always change it to /32.

Hi Karthik,
is there anyway that I can use the extra ip's then or are they effectively useless?

Hi Louis,
That behavior is only for the IP address that you have assigned on the interface..... You can use the rest of your IP's for NAT/PAT usage purpose.
