ddclient multiwan and dnsomatic

[emb]

Hi there,
I'm new in the forum but I've been using Opnsense for a long time.
I'm having some problems to use ddclient to update my wan ip on dns-o-matic service. I'm using two wan interfaces both setup as tier1 (round robin). I've configured ddclient (native mode) to update my dynamic ip address on dnsomatic service. The first interface updates without any problem but I'm getting an error on the second interface; dnsomatic tells me that "The IP Address you have supplied to DNS-O-Matic differs from the IP Address that you are coming from". So, I'm trying to update the ip related to wan2 interface but I'm using wan1 as interface (it appears as active on system gateway configuration. I've enabled the option Allow default gateway switching on system settings general.

I don't know what I'm doing wrong. Please help me.

Thanks in advance.
