Multi Dyndns / Multi WAN

[aimar]

Hi Guys

Small problem i hope you can help with. In south africa we have two types of bandwidth we can purchase. Local Only and International, Local only gives us access to sites in SA ONLY and International is the normal type.

I want a DYNDNS account on both my local only and International PPPOE accounts, the only problem being that when the local only account tries to update it can't reach the Dyndns servers as the account only has access to local address in South Africa.

Is there any way i can direct all DYNDNS updates through a specific WAN port or have you guys got another solution for me? Any help would be appreciated
