Nope, but then I haven't been monitoring your network.

Get to OpenVMS VAX V7.3, if this is a hobbyist system.   The kit is 
available from HPE, via the Hobbyist Program, as a download.

The usual trigger for this has nothing to do with OpenVMS or any other 
system, it's a setting in whatever ISP modem you were using, and 
particularly one that wasn't carried over into the new modem.   Port 
forwarding, or  virtual server, or some other such nomenclature is 
commonly used.    Some ISPs can also block inbound Internet network 
traffic into a local system as a matter of course, when the inbound 
network traffic is destined for a residential (dynamic) tier of service 
connection.   These ISPs will either open the traffic on request, or 
they can require an upgrade to a business-class (serve) service tier.

The modem controls remote inbound access, or whatever firewall or 
bridge or router or gateway box.   Not the OpenVMS VAX system.

Seems that either the zip archive is corrupt — some network transfers 
and network glitches can cause this — or you're running a fossil 
version of zip and unzip.    zip 3.0 and unzip 6.0 are the current and 
miniumum versions that anybody should be using now, so check that.
