Dear Everyone,
My network used Astaro Security Gateway 320 and NAT for email Server in Internal Network for WEB MAIL ACCESS. WEB MAIL use HTTPS (port 443).
No IPS, EMail, WEB Security is active.
The problem is Dial-up Users, the remote users using modem dial-up 28kbps. They can't access to WEB MAIL because the Request Time-out Error. They are still receive the Certificate from the Mail Server but can't access to the web page.
The ADSL Users is ok, they can check web mail very well.
And when change the ASG 320 by Netscreen 5GT, everything is ok. The dial-up users can check web mail very good.
What's happen?
Maybe the packet timeout of ASG is reason.
Someone can fix it, please help!
