Why would you not just use the fqdn for your time machine? What needs to talk to the sonos devices - just put them on the same L2.

@xenicle said in Can't access machine connected on my isp router from pfsense LAN: from it I can ping the WAN network IP 192.168.1.1 Do you mean the LAN IP there? Because then you said the WAN subnet is 192.168.2.0/24. I would not expect a client in the WAN subnet to be able to ping a client in the LAN subnet unless you have added firewall rules to allow it and a static route to the WAN side client. Without that it will just send traffic to it's gateway rather than via pfSense. Steve

Confirmed. https://redmine.pfsense.org/issues/9807

Yeah, you might consider using gateway groups there instead so that if you do get a failure clients using that gateway failover to another one. Steve

@stephenw10 Gmail limit is something around 500 emails a day. I was using single email accounts for all my sites. Service Watchdog was also monitoring dpinger for sites having multiple WAN. Due to heavy rains WAN connections were quite unstable. So it generated lot of mails. Anyway the real issue is neither Service Watchdog nor FreeRadius, the problem seems to be created by squid (as pointed by @stephenw10 in previous thread) . I am using transparent https filtering. Read about it https://forum.netgate.com/topic/112247/squid-use-all-memory-ram/43 https://forum.netgate.com/topic/136907/problem-with-squid-https-ssl-interception-consuming-all-memory/8 When I manually restart squid it stablises. As a workround, I am planing to use php script provided by @remzej , till something better comes up. Regards, Ashima

A lot of ISPs do that. Usually the modem locks to one MAC address and resetting it will allow a new MAC to be used. Some ISPs log that upstream though and you have to call and get it reset. Check the dhcp and system logs when that is happening. Something will be logged there. Steve

Erm no, that won't do a time limit. That's just time based rules. You need to use Captive Portal and radius accounting to achieve this sort of setup. Steve

10$ dif for 200 vs gig - yeah that is a no brainer.. What I would go for gig as well at that sort of price point and difference.. What I really want is the up.. But if I went gig from my 500/50 it only goes to 1000/100 - and its like 20+ more a month.. And I really can not justify the download side.. I have no real use for it, and the up is only for my friends and family to share my plex.. And 50 is handling the current load without any issues. But if I could get 1000/1000 I would jump on it for sure if only 20 more, for 10 = no brianer.. So if your going to do gig/gig - 1100 prob bit under powered.. 3100 would be what you would want. Just ordered 4th 3100 for work ;) pretty happy.. Just wish they would let me use them for some other devices with more umph... Its been a slow process.. But out of the blue my team lead said today - hey order another one of those firewalls ;)

Can you test in a 2.5 snapshot? Or against a more recent FreeBSD directly? Steve

@inHell said in How to configure? (Fritz.Box - Proxmox - Pfsense): Do I understand it correctly that the default Gateway is for using Internet and talking to the "main" Almost. pfSense sends any traffic which has a destination address outside of the subnets defined on its own interfaces to the default gateway. So yes, packets to the internet are sent to the default gateway, however, packets to any other subnet which are not known by pfSense as well. @inHell said in How to configure? (Fritz.Box - Proxmox - Pfsense): Another Gateway would be the 30.1 for the internal LAN connections in the Lab-Network? You must not set a gateway on the LAN interface. You have to remove this again. Additionally you have to set the "FritzBoxGateway" as default to get upstream traffic work. @inHell said in How to configure? (Fritz.Box - Proxmox - Pfsense): And the static route i can just delete in the FB? As stated above, you have to decide if you want to set up a routing a NAT network environment. If you prefer routing you have to add NAT rules for incoming traffic for the 30.0 subnet on the FB directly by using the device IP addresses out of 30.0. In this environment you will still need that route on the FB and you should turn off NAT on the pfSense. If you use NAT you don't need that route, you have to forward any traffic for the 30.0 subnet to pfSense and on pfSense you have to add further NAT rules to forward the traffic to the destination devices. However, all that is not necessary to get internet access to work.

is that "changing the name on a Gateway is not allowed" the same as me renaming "Interfaces/assignments" but I guess so as that's where the internet for what you want is going.. as im allowed to change it.. but thank you jimp for your input too (:

@stephenw10 Yes, bce1 statistics are not correct with pfctl (interfaces status page).

That is their reply packets being dropped because the TCP state outbound to them had already been closed. That's quite common and usually nothing to be concerned about: https://docs.netgate.com/pfsense/en/latest/firewall/troubleshooting-blocked-log-entries-for-legitimate-connection-packets.html Steve

In the Custom Options Before Auth field in the Squid general settings. [image: 1569848769553-selection_700.png] You can only specify an IP there, you can't use a gateway group. If you need Squid to use a gateway group you can leave it as default where it will use the system default route and then set that as gateway group in System > Routing. Steve

OVH do weird things. Like that might be the actual gateway they are using completely outside the WAN subnet. If pfSense can connect out, ping arbitrary fqdns, but clients behind it cannot it's probably a NAT problem. The default outbound NAT setting, auto, should work though. The default dhcp settings should give reasonable values to clients. The default LAN subnet should also work. If any of that has been changed from the defaults the clients might have bad subnet or route. Check that. Steve

Most likely: The LAN subnet or the DHCP server MAC address changed and now Windows sees it as an untrusted public network so is blocking requests from other clients. Steve

ARP movements are usually either some sort of load-balancing, like an actual load-balancer or teamed NICs in a server sharing one IP, or Apple's Bonjour sleep proxy. Check the OUI to see if it's Apple. However it can also be an IP address conflict if two hosts are set to the same static IP. Check what those MAC addresses are on your network. https://docs.netgate.com/pfsense/en/latest/monitoring/arp-moved-log-messages.html Steve

If you're using swap at all you have a problem. pfSense should not use swap in normal operation and if it does performance can be very degraded. Work out what is actually using your RAM and tune that out. Steve
