How to copy data in identity column?

I have a table with an identity column in a server and have a other table with same structure in another server.. Now I want to copy all data from one table to other table but I can't help it...

I have already created a linked server..

I use this:

insert into [server].[database].[dbo].[table1]
    select *
    from table2

I also use this query without identity column in the place of *

insert into [server].[database].[dbo].[table1]
   select column1, column2
   from table2

What should I do ?
