To do this we have installed a second ethernet card (fxp1) with an internal IP address. There is also a second dns server on the internal network which handles internal dns queries. When email clients connect to the POP server via the router the address is translated and all works well, but when connecting via fxp1 (with appropriate IP addresses etc. configured on the client machine) the connection seems to take a huge amount of time, before eventually making a connection. Once connected, normal transactions occur as expected. Similarly, telnetting to the external network address works almost instantaneously, but telnetting to the internal address incurs the same sort of delays. This doesn't seem to be dns related since the same delays occur whether using FQDNs or IP addresses. The machine is running 2.2.2-R with 2 intel etherexpress cards. any thoughts? cheers, Carey Nairn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
