The 28-year-old, who is a free agent after leaving Ashton Gate at the end of last season, has been offered a trial at Portman Road by manager Mick McCarthy.
The Ipswich boss is keen to bolster his goalkeeping options, according to Sky Sports News.
Gerken has linked up with the Town squad for their pre-season trip to the Republic of Ireland and could feature in their friendly game against Shelbourne.
