How can stop Pix from tearing down my TCP connection in 4 seconds?

[mukumucisco]

My Pix 515E model tears down my TCP connections in 4 in a very short about 4 seconds even though the timeout conn half-closed is 0:10:00 (10 minutes). How can I prevent the Pix box from tearing down my tcp connnections so fast? Below are my timeout settings:

timeout xlate 3:00:00

timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 rpc 0:10:00 h323 0:05:00 sip 0:30:00 sip_media 0:02:00

timeout uauth 0:05:00 absolute

arp timeout 14400

telnet timeout 5

ssh timeout 5

Can you provide an example of what you are talking about? Syslogs with timestamps would be the best way to illustrate this.

It turns out that this could be a problem with the application I am using - it's unable to connect to my server using ip addresses and has to use computer names (DNS). But I don't know how to set the Pix to allow clients to use computer names (i.e., DNS names). Any ideas how to do this?

DNS is UDP/TCP port 53. This has to be allowed through firewall. Workstations must point to a valid DNS server.
