I'm just wondering is it possible to use Wiznet812MJ to configure it so that it can work with DynDNS?
The Wiznet812MJ module (say 192.168.1.2) is within a network which is linked to outside world with a router which has a dynamic IP.
How can I access the Wiznet812MJ module using internet since the router IP is non-static. Can we use DynDNS or something like that?
What I need is I want to use internet to access the Wiznet812MJ. Is that possible?
Hello cs,
It sounds like the '812MJ is behind a router (which probably gets its IP address via DHCP from your ISP). How does the '812MJ get its address? Are you using DHCP with your router or are have you assigned a non-static, private IP (for example, 192.168.1.100).
If you have assigned the '812MJ a fixed, private address, you can set your router up for port forwarding to your '812MJ.
Many routers already support one of the dynamic DNS protocols so your task may be as simple as enabling it. If your router does not, the link below describes the protocol required to update DynDNS.
My guess, though, is you have everything you need.
Good luck,

To add to what Michael says, if your router itself gets dynamic rather than static IP from your ISP then you may well find that the router itself has the built-in capability to do DynDNS. My old Netgear DG834G had this, though I don't think my current SMC router does.
