IT seems your cable modem is loosing it's connection intermittently.  When the motorolla modem does not detect the coax (WAN) connection, it will unbridge the two interfaces and hand out dhcp ip's in the range of 192.168.100.x.

jimp, I installed version 1.1.1 of arpwatch but I staill get the RFC warnings and it doesn't send any email messages.  For the present time, I have disabled email notifications in arpwatch and removed email server name and email addresses in System -> Advanced -> Notifications to stop the messages in the system log. Let me know if there is something else you want me to try, just remember I'm still new to pfsense.  I like what I've seen so far and plan to stay with it.

@mattlach: So, #1 appears like it might be related to this issue with interfaces cycling.  Trying to use the fix there, but struggling with how to do it. Yep, definitely fixed my interface connectivity problem (#1) using the information in that other thread. Still can't get any WAN actioin from the LAN side though. (#2).  Any thoughts? Thanks, Matt

Upgrading to the new version could be useful. FreeBSD 2.1 It should be, I don't expect. A small risk But of course you need to configure 2.0.and 2.0.n copy to ensure income.

I dont think you need to have a bridge. If you have a pfsense box setup and routing traffic on your lan already, then you can plugin your "wireless router" to the switch, turn off dhcp, give it an ip and go. Otherwise, get wireless card, add it to you pfsense box. add the interface. https://doc.pfsense.org/smiller/add_wifi_interface/Add_WiFi_Interface.htm

It should work like you describe. On OPT1 does the client get the right netmask? The right default gateway? The right DNS? From a client, can you ping the pfSense OPT1 IP? traceroute 8.8.8.8 - where does the problem come? If you plug a PC directly into the OPT1 port with a cable, does it all work?

Ok, so you have two DSL modems? Two routers? You say they are both connected via a single NIC using a switch? I don't think you can do pppoe directly from the pfSense box in that setup. You can do two subnets and static ips behind routers but that's also 'unconventional'. It would be better to have 3 NICs. Steve

Switch restart and applying the correct IP settings fixed it.  Thanks people.

Thank you  podilarius I will check it….

Ok got it fixed. On the client 192.168.2.128 add this route: route add 192.168.2.0 gw 192.168.2.100 eth0 and route add 192.168.3.0 gw 192.168.2.100 eth0

When I disable the rules in the firewall for Dansguardian those files download no problem.

Hi all, I'm hoping to get this thread going again if possible? - after reading the forum rules I thought it better to try here again before creating a new thread. I'd like to create a LoadBalancer for a dev domain for exchange 2010 CAS for use with IIS is this possible? I could do with some outline steps to get me going laong the lines of: create LAN NIC with static IP in LAN address range (10.10.10.xxx) create WAN NIC with static IP of xxx.xxx.xxx.xxx add vIP on LAN interface with static IP 10.10.10.xxx create port alias for exchange port range (1-65535) add CAS01 to server pool add CAS02 to server pool etc etc (I've done most of the above and its not working - but happy to scrap all and start again if needed) thanks in advance :)

Thanks JimP, sorry for the delay getting back. I'll try your suggestion of altering the wpad. What about a transparent setup though? how can I get access if configured transparent

Thanks for pointing this out. I had seen the syn-ack packet coming directly to the client and the RST packet send by the client because of the wrong IP… but did not think to modify the packets with the outbound nat. Surely works now... To me the loss of the source IP is not a problem (until I'll need to debug stuff), as it's from a pool of  my own servers, and the load balancer is required to prevent a single point of failure :) Thanks again :)

OK, maybe it's not related :-) We're doing more testing at the moment, and hope to get some more info up on out status page about it later today. The problem isn't tunnel specific, we're sending UDP packets and can reproduce the problem of packets not getting through.

@Gertjan: This: Cron spam (a couple of threads lower in the same forum) didn't answer your question ? Thanks for pointing it out. Completely missed that post. Again. Thanks!

"  If my pfsense box had been installed right after the cable companies modem so that the pfsense WAN address had been set by DHCP (76.26.XXX.YYY), would my default route have been the 192.168.3.1 address?" Yeah with stephen only speculation - you clearly were dicking around to get a gateway set to your own address…  In a typical setup where you were directly connected to your ISP.. bing bang zoom you would of been dhcp on your wan and default 192.168 address on your lan and not have had to touch anything and would of been working out of the box. You playing around with static on wan and changing the IP on your lan interface is where you prob got messed up. There is RARELY a good reason, and I mean RARE!! to double nat - its pointless, it is a performance hit, and yes somethings are going to have issues working with it, and is just a PITA all the way around. I would suggest you want to use pfsense as you firewall/gateway then use it as intended - if you need more than 1 network segment/vlan on your lan side then add nics to pfsense to allow for that vs using routers that nat as your way of creating isolated segments.
