Looking for a bit of help here...
For the past 3 days I've been trying to configure a Site to Site IPsec tunnel routing two subnets.
No problem whatsoever making the connection. Ping works, pinging with -l 25000 works, etc...
The issue comes with file transfers, etc... When copying a file using SMB (Windows File Sharing), sometimes the transfer will work, but halting 50%, sometimes it won't start at all.
Transferring files via SCP (SSH) same behavior, usually transfers around 276KB before halting and freezing, a few times I can transfer over 50MB, but it ultimately freezes. I've noticed that doing a tcpdump and analyzing in wireshark, there are lots of retransmissions, and "Previous segment lost".
Keep in mind, I can load webpages across the link, make VoIP calls, etc absolutely fine...
I've been reading up about how MTUs may cause this issues?
My ISP, and everything supports 1500, the ASG is setup as default at 1500 (I haven't changed anything). After reading about possible MTU problems it says I should lower it... Does this mean I have to change the MTU on all computers, servers, routers on both subnets? Won't this cause issues if I communicate with systems on the internet which use 1500?
I'm not saying the issue is an MTU related one, it's just the only thing I can think of. I've troubleshot everything else...
Any help would be appreciated! Thanks!
(And PS. I've even done a factory fresh install of the ASGs to make sure that no configuration changes I have made or have setup are causing the issues)
