Hi All,

  Well, I've had a stab at this, but haven't managed to get it going just
  right.
  I now have a batch of 8 IP's on a /29 subnet.
  My ISP has said, make your router 62.3.114.254
  You cant use 62.3.114.248 or 62.3.114.249
  62.3.114.250 - 253 are available to you.

  My linux box has booted up, and assigned its self on ppp0 to have
    62.3.114.254, P-t-P of 62.3.82.2 and netmask of 255.255.255.255.


  I have setup my dhcpd to have:
     A network address of 62.3.114.254, netmask of 255.255.255.255
     An address range of 62.3.114.248 - 62.3.114.255

     But it moans that address range 62.3.114.248 to 62.3.114.255 is not
     on net     62.3.114.254/255.255.255.0

      Have also tried with netmask of 255.255.255.248

    I have made the mods to my shorewall conf - assigning the local_net IP in
    my params as 62.3.114.254/29.

    But I guess as I cant get my dhcp assigning my ip I cant get that far :(

    My eth0 interface is setup as per the ppp0 interface, although it has
    a broadcast address    of 62.255.255.255 (?) and a netmask of
    255.255.255.248
    If i turn off dhcp my other pcs can ping the firewall router and use
    the web.    So half the hurdle is the dhcp ide of it I think.

    I have emptied my masq file, which i no longer need :)

    Aside from that ive made no other changes to my shorewall config :)

     Thanks for any help, i guess it may be slightly ot ish with that
     dhcp thing.

    Andy
