We have connected VPN using ISA and presently we don;t have any lease line, I am using dyndns.org to refresh my dynamic ips to dns names.
Presently I am facing some problems, every 5 minutes it is refreshing ips and for communicating with router it is taking around 5 minutes.
Hence VPn dial-up users sometimes has to wait 5 minutes and it is quite annoyable. I have a ADSL router which is supplied by our ISP called Aztec.
May be this issue is with router issue and is there any other better solution for this.
Please somebody if somebody got any solution for this
