I have two sites. Site A and site B.
On site A OPNsense is the edge device. It has a DHCP WAN cable connection and MTU ping testing has verified my MTU settings of 1420 and MSS settings of 1380 are what I need. The WAN speed is 1gbit down 300mbits up. I have multiple remote access Wireguard tunnels in addition to the site to site on this device and there are no issues.
On site B OPNsense sites behind a DD WRT router which is the edge device. DD WRT has a DHCP WAN fiber connection which has the same MTU/MSS as site A. The WAN speed is 300mbit both ways. OPNsense in visualized in Proxmox on this site.
My issue is that file transfers using, wget, curl, rsync, and scp are very slow. Less than 1 megabyte a second. If I run rsync with -ahP the speed will be 100MB/s + for a short time then drop to sub 500kB/s and stay there. This happens across any host in any direction.
However, I can run iperf3 test in both directions and get speed around 200mbit/sec. If I run an iperf3 test while transferring files at sub 500kB/s speed, the iperf3 test is slower. Around 50mbit/sec ish.
Any ideas on how to figure out whats going on here? I'm lost.
