Help: Multiwan and incoming connections

[nurbed]

Sorry for my english, but help me!!!!!!!
I installed OpenSense on my new production firewall, because I activated a new ADSL on my company and I need to configure a solid load balancing and failover manager for my LAN.
My situation is:
WAN1 -> static ip 192.168.20.1 -> router1 adsl with static ip 192.168.20.254 and static public ip. All the incoming traffic from public ip is redirected to WAN1
WAN2 -> static ip 192.168.10.1 -> router2 adsl with static ip 192.168.10.254 and dynamic public ip. All the incoming traffic from public ip is redirected to WAN2
WAN1, WAN2, router1 and router2 are connected on the same switch.

LAN with static ip 192.168.0.210 and dhcp server for other pc. Gateway group with load balancing and firewall rule to redirect all the lan traffic to the gateway group. Firewall rule to correctly redirect the DNS traffic.

Now; the load balancing is ok. If I test the adsl download speed with Ookla speed test, the resulting vel is the sum of the two single vel. The problem is the upload.
Always with the same Ookla speed test, the upload test freeze on connection and no vel is detected...
I tried everything in the firewall rules: from redirect all incoming traffic to my pc, to force my pc to using a specific gateway, but nothing works...

Any ideas?

PS: with my previous IpCop firewall tested alternately on single ADSL connection without specific rules, all works... but ok, ipcop isn't a valid reference

Logically the main problem isn't the Ookla speed test, but the malfunctioning of some https connections (primarily
 home banking)
I tested a new fresh opnsense installation with only one wan to adsl connection, and the problem persists.

In my opinion, all is related with my adsl router that isn't in bridge mode, because it's the modem of the isp and this mode isn't present.
So, how do I configure opnsense to work with a non-bridge modem?
