Backhaul
-
Bang for the buck. Cost.
I'd keep Cisco if I already had it as long as it was working well, but I'd prefer pfsense if I was having to buy new as long as the functions I needed were supported.
-
My point is why not just failover on the Ciscos?

That's possibly a valid question and may be the route we end up going, but there is a little bit of complexity in our setup that does not need to be there, I am simply trying to replace a different linux system which we have little control over and is currently dieing. Once the pfsense is in place and working, the next step may be to remove them and have the CISCO's only since the pfsense cost nothing
I did not create this setup, I am simply trying to mend it whenever I am given room to do so.

Then yes, pfSense should be able to monitor connectivity to each remote bridge and fail over. Look at the techniques for Multi-WAN. Your situation will be similar.

Sure, but that's about as far as I can get. I get a little fuzzy when it comes to the routing of traffic from 1 side to the other when it comes to having a fail-over backhaul link:
pfSense2(192.168.10.66) –>> (192.168.10.65)pfSense1(192.168.10.2) -->> (192.168.10.1)CISCO(192.168.1.1)
pfSense2(192.168.10.34) -->> (192.168.10.33)pfSense1(192.168.10.2) -->> (192.168.10.1)CISCO(192.168.1.1)The current Linux box we have is in need of replacing, it has next hop routes + NAT'ing to accomplish this routing. I am not sure how to configure the equivalent in pfSense. As I said, I'm still learning networking, it's not something that was covered extensively in school. Does pfSense handle the routing if a fail-over occurs? I've hit issues where I was trying to set up routes for both links and had it give me an error due to the route existing on the other link.

Did you read the document?

Pay for PfSense support. You are getting hardware for free, and this helps the project out. As far learning if you make your diagram a little clearer might be easier to help. But PfSense can do:
1. NAT
2. RIP Routing
3. OSPF Routing
4. BGP RoutingSo you should be able to use PfSense to do what you want.

Unfortunately my understanding of networking is very basic. I am trying to follow this logically, and have come to the understanding that I need to create firewall rules to pass traffic to the correct interfaces + multiWAN gateway. Please correct me if I am wrong, good chance I will be. However if this is true, I am still unsure on setting up the rules and whether I need to explicitly account for the fact that the pfSense device is not directly connected to the end network. If someone could guide me for 1 route from 1 side to the other, that would be awesome.
I have setup and configured GW's and a Load-Balanced group + all interfaces + DNS.
This is the route it takes from our 1.0/24 LAN to our 2.0/24 LAN:
1.0/24 Network –> [1.1 [u]CISCO 10.1] –> [10.2(LAN) ([u]pfSense1)*** MultiWAN Interfaces (WAN1)10.33 + (WAN2)10.65***]
–>WiFi BackHaul-->
[MultiWAN Interfaces (WAN1)10.34 + (WAN2)10.66([u]pfSense2) (LAN)10.98] –> [10.97 [u]CISCO 2.1] –> 2.0/24 Network
Currently I have a floating firewall rule in place set to:
Pass
Interfaces: WAN1 + WAN2
Direction: out
Protocol: any
Source: 1.0/24 -- (Using an alias with multiple local networks)
Destination: 2.0/24 -- (Using an alias for multiple remote networks)
Adv. GW: MultiWAN GW'sDo I need to add incoming rules? additional rules? Is this rule even correct?

What are all the netmasks everywhere?
You will want to disable NAT, too.
You can just disable NAT and add pass IPv4 any source any dest any rules to all the pfSense interfaces in question.
Do new connections need to be established in both directions? If so you will need to configure "Multi-WAN" on both pfSenses, with each side testing both links and failing over if necessary. I've never done that before but it should work.

Thanks for the input, I will try disabling NAT. And yes, I don't see many examples of a loadbalanced backhaul on the internet, maybe my searching skills suck, idk.
And yes, I will multiWAN the remote site possibly later today if I can at least get this side configured right. I have to drive there since I screwed up a rule and lost connection, with no IT staff at that location /sadface.Could you be a little clearer on the "pass IPv4 any source any dest any rules to all the pfSense interfaces in question"
Are you implying a single rule Any Source any Dest + All Interfaces? This is confusing me since there is the MultiWAN GW.
Interfaces in question? LAN + WAN1 + WAN2?
Remember I am learning. So treat me like I'm stupid.As for the net masks:
1.0/24
2.0/24
10.0/27
10.33/27
10.64/27
10.97/27I did not set up this network, clearly.

Pass rules just let traffic into the interfaces. They have nothing to do with routing. The rules, however, can set gateways which DO affect routing.
What are all your pfSense interface names on both sides and what are they connected to?
While you're at the remote site you should assign someone local and show them how to log into pfSense (make a bookmark) so you can talk them through fixing something without having to go there.

Unfortunately that's not an option, the last time I asked the most technical person there to do something, walked him through it, he ended up changing the IP address of the machine to the IP of the server that he was trying to connect to. I was having him change the IP and DNS of the machine since it had been configured for a different network, and he was trying to connect to a terminal server on our side.

And all of that is currently up and running? You just need to add failover?

Currently our system we have is "functioning" but it doesn't do it very well; it doesn't handle load balancing/failover/link aggregation very well at all. Also 2 ports are dead on the remote side, possibly due to a surge from the cable modem.
I will know later today if the pfsense box is working if I am confident with the current rule setup, I will drive to the other location and fix the box there and mirror the rules.
I have set the 2 WiFi WAN interfaces up on the same tier. From my previous testing they should have roughly the same throughput, though 1 varies wildly. I'll need to do some fine tuning later once I actually get the link up.
So again, could you clarify my question about your comment in the previous post for the rules. And when I set the adv. GW –> MultiWAN setting for the rule, I have to choose either in or out, do I need to setup both? or OUT for LAN (what I already set up) and IN for the WAN's?
Also, thank you for responding to my post and trying to be helpful.
-
In/Out is for limiters and is totally unrelated to multi-wan. All you have to do is set the gateway group in the rule.

Well that's where I get confused because when I set the GW group for the rule, it says I need to state a direction IN/OUT.
Could you clarify "the rule" it seems I don't need to set IN/OUT when setting rules on individual interfaces vs a floating rule.
So which interface should have the GW set? the WAN's? with ANY source to ANY dest?
I currently can ping from my computer the WiFi2 Interface, the WiFi router, but not the remote WiFi router or Interface. The pfSense box CAN.
Granted those are not critical to access, however if I cannot access those with the rules I have set, I'm skeptical of reaching the 2.0/24 network over the WiFi.

No idea what you're talking about. See the attached. All you have to do is set the gateway group. If it's doing something else, fix your javascript/browser. All of those advanced sections are independent of each other.

Yeah I did that already, all I'm asking is which interface this needs to be done on, or set of interfaces. Earlier you said interfaces in question, I'm trying to figure out which ones. Maybe I have the right config and something is wrong with my wifi router, but I can't ping the remote one from my PC but I can from the pfsense box.
-
Well I guess my rules are fine, I for some reason cannot ping the gateway on the remote side as well as the wifi router, however now that I have fixed the pfsense box rules, I can connect to the box from this side. cannot ping any of it's interfaces though, or the remote network
-
You need static routes to the remote network. Did you allow any traffic or just TCP/UDP? If the latter, it will block ICMP (ping).
