strange bind dns resolve problem after firewall reboot

[Götz Reinicke]

Hi,

we have two linux servers, one RHEL4 as a Internetgateway, a second 
still running FC1 for DNS.

Usualy everything is running fine, dns queries are fast and surfing in 
the internet is no problem until I reboot the firewall ...

After rebooting the firewall dns resolves take up to 5000 seconds if i 
try e.g. a dig www.yahoo.de or whatever from the dns server. Using my 
local webbrowesr sometimes failes to get the dns name resolved.

If the dns server gets the "diged" ip, browsing is fast as usualy ...

Any ideas, what could cause the "firsttime" resolving delay?

DNS-SServer:
Fedora Core release 1 (Yarrow)
kernel 2.4.22-1.2199.4.legacy.nptl
bind 9.2.2.P3-9

Thanks for hints!


Regards
