Of the three ISPs in my area that I have used, all of them allowed inbound traffic and either had useful controls in their routers or didn't supply a router, just an ethernet handoff. RCN, Comcast, Verizon.
All of them filtered out the SMB/CIFS ports.
Two of them filtered outbound port 25; one of them was willing to open it with the additional cost of a static IP.

I've found that Hitron to not have any sort of firewalls (except for IPv4 NAT if you consider it as a firewall), while Huawei routers (which is not used in the US for reasons hopefully known to you) do have an IPv6 firewall that is only an off or on switch, stupidly their enterprise stuff do have advanced controls, Alcatel/Nokia-branded ones are inconsistent to say the least and the same can be said for Zyxel. I'm actually interested in checking out other routers used by ISPs, but those are the ones I've actually seen.
