Thanks Sten for the response.
Client Id (option 61) is included in the DHCP Discover Packet and I tried
for several days to parse it and use it, but the Cisco ASA concatenates its
MAC address, interface, and the hostname with a serial number, so ClientID
is unique for every DHCP Discover . Two requests from same client are
different.
So I am using HostName (Option 12) which does what I want and ISC DHCP
matches the hostname to the class "PCIWSV01" since the correct IP
172.16.147.131 is assigned first time through.
My problem is that after a lease is assigned, ISC DHCP seems like it does
not match class "PCIWSV01" the next time, but the more general "PCIWSVXX"
class and assigns 172.16.147.150. Third time it assigns 172.16.147.151.
If I delete the lease 172.16.147.131 paragraph out of Leases file, the next
time VPN client requests DHCP, it gets 172.16.147.131 again (which is
correct). But next time it will get 172.16.147.150 again, and so on.
Manually deleting the lease 172.16.147.131 paragraph out of Leases file doe
not sound like a feasible solution.
Any suggestions?
