Paul, you're asking whether the later IOS blocks SMB port to transit traffic, by default? (Or did you mean those port on/to the router, itself? I would be surprised that a Cisco router would block any transit traffic, by default.)
Yes i am asking if the later IOS blocks those SMB ports by default due to its very high vulnerability factor.
I cannot seem to find any validation, it could be a buggy IOS which I would say Cisco TAC would be my next port of call.
Also due to the lack of any real testing environment and nature of the clients business I cannot test various ios so hence the post on here to try an obtain a definitive answer.
TBH its either a buggy software or its blocking it by default, As it cannot be anything else, a simple roll back to the older ios resolves the connectivity problem regards these ports.
Please rate and mark as an accepted solution if you have found any of the information provided useful.
This then could assist others on these forums to find a valuable answer and broadens the community’s global network.
