outlook rule to forward through specific account

Dear all,
i have a public pc using outlook 2007 with several email account.
an account for internet and an account for local mail. (global@domain.com and global@domain.local)

my external (default mail) account using pop3 protocol and my internal using exchange 2003(for internal purpose only).

i want to automatically forward / redirect email received through external account to internal user/group through global@domain.local, but i couldn’t find any way in outlook rules to do it. (if i use the forward/redirect rule it will be sent through external account not through internal account).

thanks before.
