If you want to restrict access to a dir by IP via apache, you just need to add an additional line(s) after your "Deny from all", like:
Order Deny,Allow [this says, first I'll tell you to do deny, then I'll tell you who to allow]
Deny from All [You are denying everybody]
Allow from 123.123.123.123 [except this IP]
Allow from 234.234.243.234 [and this IP]
