Sorry to dig up this old thread, but this happened to me recently, TWICE. And the fix for me was to go inside lightsquid config and change the squid log directory to var/squid/log. The default on install tell lightsquid to search on var/squid/logs

You can just reassign the LAN interface from the webgui in Interfaces: Assign network ports: Use the drop down to set LAN as bridge0. However there is a strong possibility that when you do that you will lock yourself out of the box. Make sure you have firewall rules in place so that doesn't happen, or some plan to get back in! See my post here, particularly the attached screenshots. The way bridges are controlled in 2.0.X is in fact better once you realise how it works, it's more flexible. However I agree it's confusingly different.  ;) Steve

Not entirely clear what you're trying to do, can you elaborate?

Means it can't ping whatever you have set as the monitor IP (gateway IP if you don't have any set).

What do your traffic and quality RRD graphs look like? That'll tell the story on whether it's that you're just exhausting your bandwidth, or if it's a connection problem of some sort.

@luke240778: Is there a way that an admin can setup so that pfsense sends an email to a certain address whenever a certain user makes any changes?  For example, when user "a" adds a name to Captive Portal MAC passthrough list, that i get an email? Also, setting up the email notifications.. cant seem to do it with my email which is hosted by 1and1.com  has anyone else had any luck ? Is there any way to have pfSense send me an SMS text, or email when a user logs in to OpenVPN?  This would be very helpful for me.

^ exactly – it is possible for your machine to have a locally cached record for what your doing that got cached from elsewhere. Really need to understand how your resolve, and what what your actually wanting to resolve to make sure your resolving the fqdn your wanting to use correctly. a simple ping should show you what the box resolves your fqdn too, which should be the exact same thing your ssh client resolves. as mentioned before using actual resolvable stuff as example is bad.  And again I would stress if running your own local zones - I would use something that can never be resolved on the public for your tld, like .local or .lan or .localdomain -- when you use actual tlds that can be resolved public you might be having an issue where its being resolve using public dns vs locally if you don't have something setup correctly on your local nameserver.

Thanks for the explanations. All clear now  :).

@chpalmer: Id see if you can find a firmware update for your modem. Is it possible your running pppoa on the modem but pppoe on your pfsense box when the modem is bridged? Thanks for that and I had checked that possibility.  With different modems, it still dropped.  Remove the Realtek cards,,,,,,no more drops. I appreciate you taking the time to reply…........

It has nothing to do with what they're using for DNS, you have to configure your firewall rules to only permit traffic to the proxy and other traffic you need to allow directly out, and not allow HTTP or HTTPS directly out.

Yep, figured after research. Fixed.

Distinguishing a legit RDP user vs. a brute force attacker is impossible to do accurately at the network level. Nothing at the network level has that kind of visibility into RDP. Limiting the number of simultaneous connections per IP is the best you can do. That type of scenario has to be detected by the server, or something monitoring the server. To react to it, something on the server or monitoring the server could be scripted to block the IP on the firewall.

Not on a 32 bit piece of hardware.

Big Thanks to MIQ in the IRC channel!! here is how to do it for any future searches: Pf sense >firewall>virtual IPs add a new rule: type ip alias, wan interface type network (IP address/subnet mask) save and apply Pf Sense >firewall>nat outbound tab, save in manual mode then add a new rule: leave do not nat unchecked. interface wan select protocols source (your internal server) destination any translation choose your alias save and apply. move rule up or down in the outbound mappings. If all goes well then that box should go out on the IP specified in your alias good luck

Thanks a lot :-)

@johnpoz: "Modem is connected directly on pfSense WAN card" Depends if what your calling a "modem" is really a modem and not a gateway.  What is your pfsense wan IP, does it start with 10.x.x.x, 192.168.x.x or 172.16-31.x.x ? "I have now tracked the problem down to the squid proxy" thought you said they could make it work for you since they changed something? Modem is the real cable modem. IP of wan is 81.x.x.x If you watch the tests in the first post, you see the tunneling of rtmp isn't blocked. I guess they didn't use tunneling in the past, turned it on for a moment (the moment it worked for me) and now turned it back off. From what i've read flash ignores proxy settings and tries to use port 1935, 80 or 443 and if this doesn't work alot of website will try to send the data in a capsulated http packet. They don't use that method for some reason. I've tried to add port 1935 to the squid savelist but that didn't fix it.

I'll try moving ALL the load balancing to an external IP address using IP Alias and see if that makes any difference. [edit] Ok, that works. TCP Load Balancing worked fine using external IP addresses on the DMZ interface DNS load balancing ONLY works if ALL load balancing (including the TCP) uses IP Aliases. I will dig into this further and see if I can suss out exactly whats going on. Thanks all!

Why not just assign a WAN interface and then attach nothing to it? Are you running into restrictions because of the number of interfaces you have? I have a few situations similar to what you describe and I simply assign a WAN to DHCP and then just connect nothing to the assigned WAN interface.
