Well, for anyone else that may run into this... the problem was that a Firewall Rule is needed. I was wrong to think that the VPN creation took care of that.
Firewall Rules, IPsec is where it had to be created.

@velupazhani said in Not able to access Network Printer which is in PFSence:

except Network Printer.

And does this network printer have a gateway set.. I have seen it countless times on customer sites from very small.. To huge corps with hundreds of vlans - printers don't have gateway set. So no you can not talk to it from another vlan.

Had 1 customer - hundreds of printers in the building. Not freaking 1 of them had a gateway.. Only reasons printers worked was of proxy arp set on their core switch..

Bet you beer - printer doesn't have gateway set ;)

@viktor_g i couldnt get anything from that link, could you please guide with more details/

@clarknova we saw this in opnsense as after switching to VTI. SMB stopped working over ipsec. hard to track down. it worked like half a year, then problems started and it was kind of reproducible. pings works, SMB browsing too. SMB access timeout. reverting to classic ipsec solved the issue. i assume we did tunnel VTI back then, although the freebsd bug mentions transport mode. maybe it hurts both modes. why i wonder how pfsense is affected by this open freebsd bug as well. i would like to use VTI soon...

@viktor_g Hello, I've seen that too but it didn't help me. The solution was to reconfigure the vpn to IPsec IKEv2 and everyone is happy.

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?

HI, and can able to help with my issue, please... This was my Task Give In my work as I'm in my training Period

the Give to me was site to site vpn configuration between pfsense and cisco asa 5505

Pfsense(router)------(192.168.10.1)--switch--->to pfsense
Pfsense------(192.168.10.1)--switch--->to ASA5505 (the to cable give to me was from the same switch (same gateway)

lan cable 1Pfsense--wanIP(192.168.10.175) Lan IP 192.168.20.175-DG for my pc

lan cable 2 asa -- wanip (192.168.10.150) Lan IP 192.168.30.150 DG for my pc .. this was my set up

below I will mention my as cli

pls help me

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