EOIP Tunnel performs sporadically

Thu May 05, 2022 8:12 pm

Version 7.1.3
CCR1036-8G-2S

I have a simple EOIP tunnel set up (per configs below) that behaves sporadically.
Symptoms on Linux PCs:
1. Download 3.4 Gb ISO from Internet = download speed 40-50Mb
2. Cancel download and try again - download speed 300-500 Mb
3. Download a few minutes later = Download speed 300 Mb+, then Failed-Network error warning.
4. Download a few minutes later = Download speed 40-50Mb
5. Download same ISO from Windows server, across vlans and WAN= Download speed 300+ Mb
6. Running same tests on a Windows Laptop (download from Windows share) shows download speeds up to 47MB, but halfway through speeds drop to 0 and start climbing again after 30+ seconds of nothing.
