Hallo I have a linux name server (x.x.x.x) with a number of second level domains. If I ask for the name using nslookup, my server knows both name and IP address. Any other name server, except NS with secondary registration of my domains (y.y.y.y), returns IP address if I ask the name, but doesn't know the name if I ask the IP address. Name Server is behind the packet filter on CISCO router and there is second linux packet filter running on NS. I'd like to know, if both kinds of question to NS are to the same port and I should look for the problem outside my net or I have wrong configuration of packet filters or NS. This is part of access list on cisco router: permit udp host y.y.y.y eq domain any (156404 matches) permit tcp any host x.x.x.x eq domain (15172 matches) permit udp any host x.x.x.x eq domain (275023 matches) permit tcp any host x.x.x.x eq tacacs (82158 matches) permit udp any eq domain host x.x.x.x (29 matches) deny ip any host x.x.x.x log (269 matches) Thank you very much s uctou Hanus Hrabak [EMAIL PROTECTED] - [To unsubscribe, send mail to [EMAIL PROTECTED] with "unsubscribe firewalls" in the body of the message.]
