Hey group, I am working on getting some QoS on our network and today was my first shot and I wanted to have the experts double check my work please as I'm not 100% on some mappings etc. Our setup is as follows:
SA540 (Site 1) IP/SEC VPN SA 540 (Site 2) TC Server at Site 2 on VLAN2
I understand that QoS is applied to the WAN interface and the VPN tunnels correct? So in this case I need the traffic optimized for going over the VPN tunnel. I am using for this exercise RDC on TCP 3389.
SA540 Site 2
Firewall --> Services --> Add --> RDC / TCP / Start and End Port 3389
Networking --> QoS --> WAN --> Upstream 4439 (85% of total) --> Downstream 38097 (85% of total) --> Bandwidth Profiles --> "Remote Desktop" --> Bandwidth Range -->Min 256k Max 756k --> Priority "High"
Networking --> QoS --> LAN QoS --> "Enabled" --> Port 1 Classify Using: CoS
Networking --> QoS --> Port QoS Mapping --> Port 0 --> Highest
(Here I assume that Port 0 is actually LAN Port 1 as it is labeled on the machine? LAN Port 1 is connected to a switch which feeds everything else.
Networking --> QoS --> Port DSCP Mapping --> 16 / Medium -- > 24 / Highest (Everything else set to Low)
Networking --> QoS --> Enable CoS to DSCP? "Enabled" --> 2 / 16 and 3 / 24
Please let me know if this looks good to you guys. I have RDC a High Priority because I want to give SIP traffic the URGENT priority. I also assume the QoS has to be identical on both firewalls and all the downstream switches as well? Thanks guys really appreciate the feedback!!
