I am consistenly seeing upwards of 500ms latency and over 25% packet loss on these links. Before I say something how we need to get rid of these VPN tunnels and bring these few sites over to MPLS
Jun 08, 2018 WatchGuard Firebox V200 firewall/VPN | Network World Besides determining IPSec tunnel capacity, we also measured latency and throughput with IPSec configured and with two and 1,000 firewall rules in place. IPSec tunnel capacity Re: VPN Latency is high across the VPN Tunnel Remote location is a DSL internet connection and main office is a T1. Remote location is about 900 miles from main office. Central location Antenna1-----remote peer 1 (vpn and latency works perfect) Central location Antenna 2-----remote peer 2 (vpn increases latency but ip to ip works fine). For the central location 2 these are the tests that I ran. Central Location Antena 2. Router inside: 10.10.10.1 Feb 13, 2020 · Limited access to high security No-Spy servers Best Latency in a VPN. Split tunneling is the generic term for when a VPN lets you define which apps send data through the VPN tunnel and

I had found a major VPN bug in 14.37 and older for the MX67/68. My MX65 would do 120/12 all day long for tunnel traffic, swap for the MX68 and it barfed. Any easy test is to enable split tunnel so internet speed tests are local, not over the tunnel. If you see improvements you know you are hitting the same bug, as the issue exists only the tunnel.
Jun 15, 2020 · 2. VPN Forced Tunnel with a small number of trusted exceptions. This model is significantly more efficient for an enterprise to operate under as it allows a small number of controlled and defined endpoints that are very high load and latency sensitive to bypass the VPN tunnel and go direct to the Office 365 service in this example. Pinging a vpn remote-gw end-point is not passing traffic thru the IPSEC tunnel. If you goal is to test latency thru the tunnel, you need to monitor the traffic that goes thru the tunnel. If you want a type of advance-latency monitoring and have a local-subnet allowed thru the tunnel that uses TCP, you could craft a simple checker that measures Still having high tunnel latency spikes randomly with TAP 9.21.2 on windows 7 64 bit. If replace it with 9.9.2_3, the spikes are not severe as before and seems more 'stabilize'. Using OpenVPN 2.4.0 client. For this lab, we are going to use the above topology in which there is an established IPSEC tunnel between branchG and CO-A-1 SRX devices. root@branchG> show security ipsec sa Total active tunnels: 1 ID Algorithm SPI Life:sec/kb Mon lsys Port Gateway . 131073 ESP:3des/sha1 5070fa96 7130/ unlim - root 500 192.168.9.2 >131073 ESP:3des/sha1 d56e13a8 7130/ unlim - root 500 192.168.9.2 Jul 27, 2018 · Use hping3 to determine latency or TCP packet loss problems. hping is a command-line oriented TCP/IP packet assembler/analyzer. In addition to ICMP echo requests, it supports TCP, UDP, and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features. This will help determine whether it's an issue inside the tunnel (less likely) or an issue with the overall connection (more likely). If the above testing shows you that nothing looks strange or unusual during the time periods that you see high latency, then it's time to start testing further inside the tunnel.
