I'm noticing some weird traffic behavior between these two LAN networks on opposite ends of a Site-to-Site IPsec VPN (routed IPsec in pfSense).
If I run iperf3 or initiate a samba transfer from Site 1 to Site 2, I'm getting a throughput of about 200Mbps. However, if I initiate either iperf3 or a samba file transfer from Site 2 to Site 1, I'm getting over 600Mbps. Both pfsense boxes are running identical hardware and identical packages (snort and pfblockerng turned off for these tests). Both c2758 CPUs are at the same CPU usage during the transfers.
I drew out the above diagram mainly just for myself to confirm if everything looks good and I'm not seeing a networking issue. Nor do I believe a networking either would cause this slowdown for just one direction of the connection. Am I crazy here? And if not, can someone point me in a direction to start looking for the culprit to my issue?
