Hi @morlock , many many thanks for your answer. I already had configured your Phase1 parameters, but I've tried IPSec advanced and gateway ones and It works properly! I've tested different lifetime values, 1hour, 8hours, 24hours... and it seems it works fine! Now I'm going to test if it only depends on IPSec advanced "make-before-break" parameter, just to understand what was going on. I'll provide feedback again. Many thanks mate!

@maelstrom-0 said in Incredibly Slow transmission rates over Site-to-Site IPSEC VPN: I was eventually able to solve it by backing off the encryption levels thanks for the tip. Unfortunately no improvement for me.

@balthxzar We also had this problem and it turns out that the "bypasslan" peer config is used when we have no remote/own ID matching in phase 1. The "bypasslan" config is only used if in the advanced settings the following is active: Auto-exclude LAN address Enable bypass for LAN interface IP Exclude traffic from LAN subnet to LAN IP address from IPsec. As soon as this was disabled our peer config selection failed. With fixing our IDs we got the correct "peer config selection" and PSK worked as expected.

@damo112 said in Clients connect with the same IP address: Sorry I misspoke about ip, what I really meant was that if my ''client number 1'' takes an ip, I disconnect ''client number 1'' and I connect ''client number 2'', is it possible that he takes the same ip of ''client number 1" ? Ah, ok, that's different. Yes, it's possible. The OpenVPN servers assigns IP's somewhat like a DHCP server, although I guess its just takes the first IP out of the free OpenVPN-client pool with IP's. When two clients connect, they don't have the same IP, right ?

Okay, I think i have found the problem, in the IPsec > Pre-shared keys, it's possible that the key you entered is blocking the connection of other workstations. In any case this was the cause of my problem. I share this solution if people have the same problem as me. Bye ! =)

Can no one help me or point me in the right direction?

I solved the problem. After installing the patch, I added Pre Shared Key on the IPsec side and the problem was resolved.

@mr_jinx bro is that possible to installed pfsense server via vmware workstation?

@cre8toruk I'm having a similar issue with 2 different sites with a 5100 and 7100. They're both on the same ISP, and a tech there has indicated there's a firmware glitch with the modems affecting VPN / VoIP traffic... Everthing else works, pings through vpn, vpn doesn't drop, internet slows down a lot - but still up. SMB and Domain Auth seems to be affected the most. Reseting the modem seems to fix the issue for a while, but then it'll stop working for SMB shares usually some random time later. Have you had any luck finding your issue?

@barronc Yes but they look like log spam that would do nothing to help solve a problem at "normal" layers. I troubleshoot IPsec on pfSense all day every day and the aforementioned log settings give me everything I need.

@gonecamping I am a flipping idiot. ;-) If I put the WAN IP as the NAT/BINAT address and then LAN as the local network, it worked. P2 still works and traffic flows from LAN to our customer network.
