BUG Clear OS 6 and 7 ...

I did test both of them Clearos 6 and Clearos 7 and the bug and problem it is like this :


If you will conect to VPN PPTP and try to browse some certain websites like: mail.yahoo.com , speedtest.net and a couple of more websites , The websites does not load , simply do not load at all .

I can ping and tracert successfully to the websites but the browser does not load them or produce an error. Ping work , tracert work and even trafic i see it work but page still does not load .


I did try to use the YAHOO DNS , the GOOGLE DNS , and even the provider DNS , still nothing work ... I did change the network ip's to many diferent configurations still nothing fixed this


After a couple of testing i have seen an strage setting about the mtu value wich it is 1400 ...

Does anybody have seen the bug , and did fix it somehow ? I am very shure it is something from the MTU of server side , since witout VPN work all pages and load , and wit the VPN connected does not load , but ping and tracert work ...


So the problem and bug it is the value MTU , but i do not know how to change inside the VPN this setting . It is required : Put that before exit 0 in IPUP. /etc/ppp/ip-up for me.
