port access to site to site VPN

Setup a site to site VPN between two cisco routers.

One of the site locations is unable to access ports such as https://example.com:9001

How do I let them go into port 9001?

They can ssh, ftp, telnet and everything else.

Is this a VPN issue or ACL access issue?

I put
permit ip host 10.0.0.0 host 192.0.0.0

tried adding this
permit tcp host 10.0.0.3 host 192.0.0.5
but nothing

so they should be able to access???:confused:
