Unable to receive Connection through WAN2

[Simon]

I have 1 LAN connection and 2 WAN Connections (Design for failover / load balancing )
Default gateway is not set on either WAN
I can receive the connection via Port Forwarding on WAN 1 to the web server ( Port 80 )
However with the same setting on WAN 2 ( with same port forwarding ) it wont connect.

I have been working on this for a week now, change every setting I can think of, but no luck

I need this working where either WAN connection in goes to the same server via the LAN interface
for load balancing, I have checked logs and on WAN2 when the conenction comes in it shows as
orange with rdr ( I assume that means port forward redirect )
Its not FQDN or DNS or web server binding 

I am getting to the end of things to try, really need any help I can get
Appreciated

Help !

Two different isp? Static ips? How do you balance incoming traffic? Dynamic routing protocols or round robin dns for your webserver?

You have to ask yourself how traffic should know that WAN2 should be used.

Hbc
Thanks for your reply

The 2 WAN IPs are from different providers they are both static

for example
WAN IP 1 = 50.50.50.50
WAN IP 2 = 60.60.60.60

50.50.50.50:80 connects fine ( forwards on to the server )
60.60.60.60:80 doesnt connect ( doesnt forward )

Even though both WAN port forwards are setup the same

[hbc]

And the traffic is received on WAN2 if you connect to 60.60.60.60:80? tcpdump on interface to confirm.

[Simon]

Thank you
Yes,
I get a log entry with an rdr reference ( I assume that means redirect / port forward )

[Simon]

I think I figured out why this is happening, though I cant figure out how to fix it

As i see it any data coming in on WAN 1 routes back out on WAN 1
However I think any data coming in on WAN 2 does hit the server but the firewall tries to
route it back out via WAN 1

How do I fix this ?

Many Thanks

[Simon]

Has anyone any ideas solutions?
I have been working on this for over 2 weeks now

I need it to connect and flow back out of the WAN it connected in to
The connection could connect to either WAN at anytime

I have a Draytek 2925 Dual WAN which works perfectly under these same conditions, both WAN ports connect
I dont really want to replace OPNSense with the Draytek as OPNSense offers so much more.

Many Thanks

Further update
If I set WAN2 as default gateway, then it works, but WAN1 then stops working
So I am back at square one, how do I get them both to work ?
A connection could come in from either WAN

[hbc]

Did you check the guides about multiWAN? I think you need gateway groups and have to define priorities.

[Simon]

hbc,
Thnaks for getting back to me,
Yes, I have checked those and created the appropriate Groups and balances
I have re installed 3 times, and tried every item I can find, every single configuration
You must be able to do this, otherwise there is no point to multi WAN pointing to a single LAN
The issue is for inbound connections only

[Simon]

After 2 months, and every possible permutation and queries on forum I have given up
and concluded that inbound load balancing on multiple active WANS doesnt work,
OPNSense uses the default gateway method, eg it can only be received on that gateway
until that gateway fails and then the gateway switches to the other WAN, upon which
the WAN2 receives OK. So you can have both, but only one at a time.

I have replaced the entire set up with a Draytek 2925 Security Router, which works
perfectly across 3 WAN connections, inbound load balancing and failover.

I would much prefer opnsense, as the actual firewall is much better

Better stay with draytek. I have the impression it is the better system for your usecases  ;)
