    ^^^^^^^^^^^^^^^^

    Your server has a firewall running, and is refusing to allow the
    laptop to talk to the nameserver daemon.

    ....


    The main answer is a firewall on the server. You can see this in the
    "admin prohibited" response (ICMP Type 3 Code 10 - see RFC1812 section
    5.2.7.1). To find out why this is occurring, look at the firewall rules
    on the server "/sbin/iptables -L". The other solution would be to fix
    the DHCP server so that it hands out the skanova.com name server addresses.

    OK, I've had a look at the fire wall and have opened up "domain". That
    improved the situation bit. I can now do a dig from the laptop via the
    server and get reply. However, I still can't get a web page up on the
    laptop.

    This is my new iptables:

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination
    RH-Firewall-1-INPUT all -- anywhere anywhere

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    Chain RH-Firewall-1-INPUT (2 references)
    target prot opt source destination
    ACCEPT all -- anywhere anywhere
    ACCEPT icmp -- anywhere anywhere icmp any
    ACCEPT ipv6-crypt-- anywhere anywhere
    ACCEPT ipv6-auth-- anywhere anywhere
    ACCEPT udp -- anywhere 224.0.0.251 udp dpt:mdns
    ACCEPT udp -- anywhere anywhere udp dpt:ipp
    ACCEPT tcp -- anywhere anywhere tcp dpt:ipp
    ACCEPT all -- anywhere anywhere state
    RELATED,ESTABLISHED
    ACCEPT tcp -- anywhere anywhere state NEW
    tcp dpt:ftp
    ACCEPT tcp -- anywhere anywhere state NEW
    tcp dpt:smtp
    ACCEPT tcp -- anywhere anywhere state NEW
    tcp dpt:ssh
    ACCEPT tcp -- anywhere anywhere state NEW
    tcp dpt:https
    ACCEPT tcp -- anywhere anywhere state NEW
    tcp dpt:http
    ACCEPT tcp -- anywhere anywhere state NEW
    tcp dpt:domain
    ACCEPT udp -- anywhere anywhere state NEW
    udp dpt:domain
    REJECT all -- anywhere anywhere reject-with
    icmp-host-prohibited



    This is what I get on the server (using tcpdump) when I do a dig on the
    laptop.

    And this is what I get on the server (again using tcpdump) when I try to
    load up a webpage on the laptop:

    192.168.1.253 is the address of the laptop. What does "oui Unknown"
    mean? Any idea why dig works but not web access?

    Again, thanks for your time with this.

    Looks like they do ;-)

    Next Russian doll :-

    I had a look at masquerading and mainly followed the stuff at
    Masquerading-Simple-HOWTO except I did the bit for ppp but put my eth1
    interface in as I get my address dynamically.

    That helped a bit. I can now get web pages up on my ISP. However, I
    can't go further on the Internet. All I get is a time out. I guess
    that's still a masquerading problem?

    Thanks again for your time.

    I got a dump of both eth1 and eth2:
