i have 450 Digi transport wr21 routers in IPsec vpn with two VPN contcentrator V7400 (VC74-00S2-DE6-SE) in vrrp mode.
When i ping LAN port of V7400 there is less lost packets than when i ping vrrp address.
Also, when i ping through vpn tunel there is a lot of lost packets sometimes 70%.
Please, can you give me any instructions how to solve this issue. My production is suffer.
