    Local loopback with new business router


    Hello All
    I recently bought a new business class router for my network. I currently run 13 websites, a DNS server, mail server and ftp server on Redhat 9.0 and currently have only one ip address. I upgraded the router because the old home-class linksys was choking on all the traffic. I could browse all my websites using the linksys and recieve mail from my mail server behind the lan. Unfortunatly the new router does not support local loopback so I can not check on my sites or receive mail over the lan side, although the sites and mail are up and running on the wide area network. I heard that there is something you can do with the dns zone files to fix this but have had no luck yet.

    This is what my current zone files look like:

    $TTL 86400
    @ IN SOA ns1.fixit4u.biz. support.macshl.us. (
    2003083102; Serial
    5000 ; Refresh after 3hrs
    3600 ; Retry after 1 hr
    604800 ; Expire in 1 week
    86400 ) ; Minimum ttl 1 day
    IN NS ns1.fixit4u.biz.
    IN NS ns2.macshl.us.
    macshl.us. IN A 68.15.100.50
    www IN CNAME macshl.us.
    ftp IN CNAME macshl.us.
    mail IN A 68.15.100.50
    IN MX 10 mail
    macshl.us. IN MX 10 mail.macshl.us.




    Would this work?

    $TTL 86400
    @ IN SOA ns1.fixit4u.biz. support.macshl.us. (
    2003083102; Serial
    5000 ; Refresh after 3hrs
    3600 ; Retry after 1 hr
    604800 ; Expire in 1 week
    86400 ) ; Minimum ttl 1 day
    IN NS ns1.fixit4u.biz.
    IN NS ns2.macshl.us.
    macshl.us. IN A 68.15.100.50
    macshl.us. IN A 192.168.1.254
    www IN CNAME macshl.us.
    ftp IN CNAME macshl.us.
    mail IN A 68.15.100.50
    mail IN A 192.168.1.254
    IN MX 10 mail
    macshl.us. IN MX 10 mail.macshl.us.



    Thanks for any help.

    The quick way would be to add them to your hosts file like
    Code:
    192.168.0.1  mail.myserver.com
    im not very good on DNS so i will now hand over to someone else.

    same problem

    I had this same problem with my router. The easiest way i found to work around it was just to use the interneral IP numbers

    say your http server was 192.168.2.15, use that ip in firebird (or whatever) ... not the best solution, but it works
