I installed \u00a0my exchange 2010 email server<\/a> on a rented server in a\u00a0data center. I wanted to keep my remote exchange server and local client\u00a0computers\u00a0on the same domain . So i needed to install a secondary domain controller<\/a> locally and run repliction between exchange server and local DC . Since I can not afford a\u00a0separate\u00a0vpn hardware in\u00a0data center\u00a0for site-to-site \u00a0vpn,\u00a0\u00a0I just enabled global vpn\u00a0 on my sonicwall<\/a> TZ21<\/a>0 and \u00a0installed sonicwall global vpn client software on exchange server . I enabled split vpn\u00a0\u00a0 which\u00a0 is important to seperate internet and vpn tarffic\u00a0 ( I did not want my remote exchange serer use my office internet bandwidth for external communication) and I Created a vpn policy to\u00a0limit\u00a0 vpn traffic between exchange and secondary\u00a0DC only\u00a0 .<\/p>\n

Domain replication has been scheduled for every\u00a0 1 hour\u00a0 and Everything was working fine , except .. the vpn communication brakes down frequently . But on sonicwall , global vpn session shows active .\u00a0 After\u00a0 2 \u00a0hours of struggle , i finally found\u00a0 the solution for\u00a0 this.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

 <\/p>\n

The fix is , uncheck the check box\u00a0\u00a0”\u00a0enable IKE Dead peer detection” \u00a0in\u00a0 Advanced vpn settings<\/p>\n

 <\/p>\n

Also\u00a0 I had to adjust the tcp innactivity timeout\u00a0 -from 15\u00a0 to 120 minutes.<\/p>\n

 <\/p>\n

Firewall access rule –> select matrix —> select VPN to Local\u00a0 rules –>\u00a0edit settings of \u00a0any to WLAN<\/p>\n

Remote access Networks—> click Advanced\u00a0\u00a0\u00a0\u00a0 and chnage the tcp innactivevity timeout<\/p>\n

 <\/p>\n

You may need to do the same for\u00a0\u00a0 LAN to VPN\u00a0 access rule .<\/p>\n
