DNAT port forwading (SQL port UDP 1434)

Dear all,


here's my issue :

We have just bought a new XG 210 and started deploying it, all if working fine only the port forwarding,

I want to open port UDP 1434 for the SQL browser, I tried all possible combinations but it didn't work, I was able to open TCP port 1433 by using WAF, but WAF works only for TCP, no UDP,

here's the service created for UDP 1434

and here's is the DNAT rule created :


So any ideas? plz?
