the box is on a partial T1 connection. I am not using the isp's dns box I am using another bsd box for name resolution of our external addresses. these servers are on the dmz of a hardware firewall box (have select direct access to the outside world). the users computers are on the trusted side of the firewall and have unrestricted access to the dmz (however the dmz can not access the trusted). all trusted pc's are on the 192.168.0.X and have an internal NT dns coupled with our dhcp server (were on an nt domain). all the pc's on the dmz have an external (internet) ip address. right now the SMTP server can't resolve the addresses of the 192.168.0.X cause it can't get to the internal (NT) dns server, only the external that has no zones for the internal blocks. the smut server is trying to resolve the incoming connections and the trusted pc is timing out before the SMTP server gives up and allows access. I have already set the sendmail option to not resolve names and it had no effect. -----Original Message----- From: Joe & Fhe Barbish [mailto:barbish@a1poweruser.com] Sent: Wednesday, May 08, 2002 5:20 PM To: Shane Ashley Subject: RE: incoming connections You have an DNS problem, your FBSD system does not know the ip address of your ISP's DNS servers. If you are using user ppp to dial your isp add the following to your ppp.conf file. enable dns # Gets the ISP's DNS IP address & places them # in resolv.conf for reference by FBSD box. -----Original Message----- From: owner-freebsd-questions@FreeBSD.ORG [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Shane Ashley Sent: Monday, May 06, 2002 7:13 PM To: Freebsd-Questions Subject: incoming connections does anyone know how to disable FreeBSD from resolving incoming ip addresses, or how to lower the time out so that it will not take a min and a half to give up? simply put I have a SMTP server on one side of a 3 part hardware firewall using an internet ip address. then I have the internal section of the firewall (192.168.0.X) that is connecting to the SMTP server. the SMTP server is not able to resolve the addresses into names and is taking 1 1/2 min. to time out. I have an external dns that the SMTP server can use but I would rather not make unnecessary generic zone entries into the dns box. what can I do?
