@fholzer The OpenVPN IF is wide open; allows from any to any, any protocol.

there was a lack of client override settings now all is working fine

@dust1 Check this https://forum.netgate.com/post/675979

@bolvar maybe your old client - which is common added the search suffix. You should be able to push the search suffix or domain in the options for that client on the server. You mean 2.6.13? That is the current openvpn client. I think right around 2.6.something is when they changed to dco interface - that might have something to do with the search suffix of the domain you hand out? But a NS should really never answer a non fqdn qeuery.. If you don't want to use the fqdn then you client should auto add search suffixes to the query.

@crazily9892 said in OpenVPN Layer 2 with VLANs - How to Set Up?: My pfSense lets me put a VLAN tag on my L2 VPN Thank you. I tried to set the VLANs on the OpenVPN tap interface: [image: 1741165278223-screenshot-2025-03-05-at-09.59.44-resized.png] And then I added a bridge from the newly created VLAN to the existing interface which is tagged on the switch: [image: 1741165307049-screenshot-2025-03-05-at-09.59.48-resized.png] [image: 1741165309798-screenshot-2025-03-05-at-10.00.33-resized.png] The CLOUD_LAN interface has a CARP Virtual IP Address: [image: 1741165533277-screenshot-2025-03-05-at-10.05.14-resized.png] On the other end, I have a vmbr interface: 24: tap0.150@tap0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master vmbr150 state UP group default qlen 1000 link/ether e6:43:98:64:45:36 brd ff:ff:ff:ff:ff:ff 25: vmbr150: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether e6:43:98:64:45:36 brd ff:ff:ff:ff:ff:ff inet 192.168.150.1/24 scope global vmbr150 valid_lft forever preferred_lft forever inet6 fe80::e443:98ff:fe64:4536/64 scope link valid_lft forever preferred_lft forever Which is bridged to the tap0 OpenVPN interface: root@node1:~# brctl show bridge name bridge id STP enabled interfaces vmbr0 8000.107c614c4e64 no enp5s0 vmbr150 8000.e64398644536 no tap0.150 Anyway, if I try to ping the pfSense CLOUD_LAN IP address from the OpenVPN client, it does not work: root@node1:~# ping 192.168.150.254 PING 192.168.150.254 (192.168.150.254) 56(84) bytes of data.

Do you have any idea? Thank you!

@JonathanLee Not only smb needs to be accessed, but also a proxmox server, for example

@nattygreg Thanks I have attempted many trail and error tests, another one that gave me speed boosts was changing these settings. Screenshot 2025-03-03 at 21.50.05.png

@Gertjan does SafeXcel accelerate any of these ?

@justanotherpfsenseadm If the interface is configured as a DHCP client it possibly gets a gateway from the DHCP, or you've stated the gateway by yourself in the interface settings. In theses cases pfsense automatically adds an outbound NAT rule. You can verify automatically generated rules at the bottom of the outbound NAT page.

@Gertjan said in Any recent changes? Getting hard reset.: Your "/sbin/ifconfig ovpns1 172.16.255.1/24 mtu 1500 up" seems to fail. can't tell you why ..... No issues with my : I couldn't seen any reason either, so I rebooted pfSense and that seemed to clear it.

Sooo I did some extensive testing on my home box... Renew CA - use same key and same serial Renew server cert - use same key and NOT use same serial In this scenario all existing certs are valid and can connect without an issue. If I renew client cert it also connects without an issue. What is more interesting is this: Old CA was valid to today for example When I generated client cert with that CA it was valid for 10 years and NOT until today like my old CA So this probably mean that this cert, generated with old CA and valid for 10 years will also be valid with NEW CA and NEW server cert in place :) So if you have like 400 clients like I do it is IMHO OK if CA is valid for 10 years, then just renew CA and server cert approx. 2 years before expiration and take care of certs that are expiring and that's it :) And then, repeat after 8 years... Thoughts or criticism? Can it really be this simple and straightforward or am I missing something?

@FernandoScheffel said in OPENVPN site-to-site LOCAL/AWS doesnt ping between hosts only between pfsenses: I solved the problem creating a NAT Outbound rule in my pfsense server to translate local IP to tunnel IP I'm having a similar problem. Can you give an example of how your configuration looks in pfsense? I tried to reproduce it but I think I'm making a mistake in some detail.

@Xentrk no idea how you pulled this off but as soon i enable redirection rule on LAN to openvpn gateway i get wierd shit going on like very slow gui reloads suggesting loopback errors, traceroute going through vpn, but websites like ifconfig.me reporting "normal IP" for some time then al web browsers time out, but i can run succesful trace to them through vpn connection.... VPN gateway is heathy - if i set it as default gateway everything works great, except it seems to ignore firewall rules as i get open ports without any NAT rules on it's interface.

@Gertjan said in How many max VPN user supports Pfsense: @Sf said in How many max VPN user supports Pfsense: I try to evaluate, and need to understand how calculate a vpn user. Easy. You need to know what you 'consume' yourself. With out flat rate ISP price, this notion is lost. Then you need to know what others need : this question, how hard you try, can't be answered. From now on, stay at home, do what the 'working world' did during covid. And go ask others how they experiences it, the quality of their uplink to work, etc. Understand that everybody wants a "1 Gbit symmetrical" these days ^^ As shown above : 80/100 users over a 100/65 Mbit could work ... but I'm pretty sure they had to wait ones in a while to get to their 'data' ^^ Thank for answer. It's not bandwith or ISP that I want calculate, but cpu and memory needed.
