After recent upgradation from ADSL to Fiber , users facing issues with IPSec/ISAKMP traffic  . Because of this many site-to-site VPN locations become unstable . It is applicable to 3G/4G and Fiber connections , but not applicable to MPLS/Internet-IP-VPN/Static-IP/Leased-line/V-sat connections .

Solution : Use Cisco based  cTCP  ( https://www.cisco.com/c/en/us/products/collateral/security/ios-easy-vpn/prod_white_paper0900aecd8061e2b3.html ) or OpenVPN . Both of this are not using standard UDP/ TCP ports for VPN . You can use/change any port on these setup .

Summary : If you are planning new VPN setup and if you don’t have static public IP , use Cisco or OpenVPN only . All other UTMs ( like Sonicwall,Cyberoam,Fortnet, Juniper etc )  may not be stable .

Vodafone ADSL and Ooredoo 3G/4G started giving Natted IP , like 10.X.X.X ( not entirely , but it is on  roll-out stage ) . That means you may not be able to publish cameras/servers etc through such setup . Also you can not have Vodafone or Ooredoo 3G/4G connections on VPN head-end .

Solution : As of now you can not publish Camera/server on such connections . Use Qtel ADSL / Fiber or Static public IP  . If there is no such connections available ( like in Readymix factories ) call us , we can offer cloud based VPN .
