Yes, by dropping instead of rejecting ident requests. Dropping them generally causes the pop3 and sendmail daemons to wait on ident timeout. If you reject them at the firewall, (this is particularly applicable when using NAT) the daemons stop waiting for the ident packets to come back, and immediately allow the connection. The other option is to configure sendmail and pop3 to not wait on the idents. /*-----------------------------------*/ /* I live with FEAR every day. */ /* But, sometimes, she lets me RACE. */ /*-----------------------------------*/ KT Morgan Network Engineer Checkpoint Firewall-1 CCSA/CCSE Microsoft MCP Software Systems Group, Inc On Fri, 13 Aug 1999, Salatino, Dave wrote:
We installed a PIX firewall and ever since POP and SMTP have been slow to establish a connection to the mail server on the DMZ from the inside. Has anyone here seen the same symptom? TIA Dave
