I'm currently experiencing a lot of traffic congenstion on my link to the internet that causes congestion, resulting in pack loss for latency for the VPN traffic. It's a fiber link, 10MB syncrhonous with a media converter that goes from fiber to enternet. Currently there is an unmanaged switch and I would like to replace it with a managed switch. The VPN is site to site, and I would prefer to be able to apply priority based on IP address as many sites link into our VPN, some requiring more bandwidth than others. All static IPs.
WAN IP address of firewall - 184.108.40.206
WAN IP address of VPN device - 220.127.116.11
What I would like to do is force all traffic coming in and going out for the VPN to have priority over the firewall which is used for regular internet connectivity. I'd like to buffer as much as I can on ingress and egress to avoid packet loss. I've been reading about the bandwidth and prioroty commands, as well as MQC, but am not sure which direction I should take. I do not currently have a switch purchased for this purpose as I realize there are different QoS applications for different devices. Could someone advise the best path for me to take as I'm fairly new to QoS? Thanks.
