Cant enter my server anymore

[spellatra]

My server worked before and now that we have changed our rooter i needed to do again the port forward and all.

I config the config.xml all is ok

I try to enter the game but that take 0.5 sec for it to say that my server dosent work.

I go to command prompt and i do ipconfig/all my lan ip is changed *its not the same than before* i go change all my forwarded port to my new lan ip...

After i try again to connect to my server, it take like 10 sec to say me he cant connect i think im in the good way to make it work back but now im completly lost... need some help.
I use a no-ip

Like 3h i try to make it work if its not more xDD

Ty in advance all
