I have a 1721 router on cable modem on e0, vpn connection to two remote sites. Cable on e0 is dhcp makes this a little more complex. My problem is with connecting to an offsite email server from the lan behind the cisco 1721. Over a period of time approx 24 hrs we end up with outlook errors connecting to the email server. Cannot connect or something simular. The problem has been improved upon slightly by ip nat translation finrst-timeout 120. If you clear the nat table the problem is fixed instantly for another period of time only to re-imerge the next day. Any suggestions would be appreciated. Thanks! Prepaid Gift Balance
Hello Can you post the configuration of the rtr please?

does the "approx 24 hrs " match with the DHCP lease on interface e0 ? (lease time /renew time) did the DHCP address indeed change ? or did the DHCP renew process interfere with the existing NAT translations ?
