Low Internet Bandwidth (Internet Over VPN) Tunnel from India to USA
Hi, We have a Two Branches India and USA (Head Office) configured Ipsec VPN tunnel between them and enabled Internet Over VPN for India from USA on Sonicwall Firewalls. We have 100Mbps leased line but when users in india access the internet getting throughput 5-10Mbps download and 2-3Mbps upload with latency approx 260-300ms. I have crossed check with ISP about the routing there is no issue found and nothing wrong with Firewall configuration. Can anyone help and suggest the best architecture to resolved the Bandwidth issue.
