We haveВ a CCTV server in each location doing the recording and another server in location A controlling the management/permissions side of things.

AllВ devices/phonesВ and serversВ are talking but we are having an issue with a plugin forВ our CCTV software Milestone. I have managed (or so I think) to get the VPN connection to work. The XTM515В runs over a leased line(100mb up/down) in location A, XTM26В runsВ a temporary ADSL line(5mb up/ 1mb down) in location B while we wait on a point-to-point connection to be installed.

Reply from 192.168.1.Recently I have set up a BOVPN between two geographical siteВ locations with two Watchguard FireboxВ devices, XTM515 and anВ XTM26 with pro license. Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), Packet needs to be fragmented but DF set. Minimum = 50ms, Maximum = 189ms, Average = 85ms Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),ДЄpproximate round trip times in milli-seconds: Apparently he'd never made any MTU changes based on fragmentation. And the last question, does it even matter? I brought this issue up with a local Cisco support contractor a few years ago, and he shrugged it off like I was speaking a foreign language to him. So do I need to tweak everything here and there down to 1272? To make matters worse, I did a fragmentation test across the MPLS link to our data center (not using VPN tunnel), and it fragmented above 1272. What about all the other switches and routers I control, other than those two ASA endpoints for the VPN tunnel, do I have to change the MTU in all of them also?

Do I need to set MTU in DHCP as well? Why would I want to optimize and prevent fragmentation at the tunnel endpoints, rather that at the source, at the PC and switch? Seems like it would suck to have to live with the lowest common denominator speed for the Internet, just because of a slower VPN tunnel for some traffic. It seems like we'd want to stop fragmentation across the entire network. Does something happen inside the IP protocol to inform the PC and RDP/Terminal Services server about this, so they don't keep trying to send 1500 byte packets? Or does that part not matter? If not, why not?

If I follow the logic correctly, I should set the MTU on both sides to 1434, right? Why is that different than the 1440 recommendation from Cisco? But getting to the other VPN site, they fragment anything larger than 1406 (MTU 1434, with the IP header). Tests show that one site can get to the web without fragmenting at 1472 (MTU 1500, with the IP header). Say I have a VPN tunnel between two campuses in different states. I read in a Cisco white paper that an MTU reductionВ 'complies with best practices in VPN networks of setting the MTU to 1440 bytes on an interface to allow for IPSEC headers.'
