Hi Experts.   I need to open all ports on a pair of old Cisco 8005 routers on a leased line.   Security is not a consideration in this particular instance.   Can someone advise me of the commands that would allow all traffic from both sides?   Many Thanks

If you do not put any restrictions, then all ports should be open (whatever you require).

Btw, ports does not work like a door that you open it. Applications open ports in device. e.g if you do not have http/ftp service in anything you cannot open port 80 or 21 yourself. That  application which will use port 80 or 21 will open it.

Do not worry about any ports in cisco routers. They should be available to you without doing anything. Still, if something does not work as expected help will be available here.

Please note you will be ONLY able to block (and subsequent selective allow) a port. You cannot open an unused/every port.

Many thanks for this it is a great help  I have a situation where from one end of the leased line I can ping devices at the other end, but I cannot connect to anything.  When I do a port scan of a device it shows no ports open, but users at the other end have full functionality, port 25,  Port 80 etc   There are no firewalls involved and have checked everything else and figure it can only be the routers blocking in some way.  From what you say, I should be able to see any restrictions on the routers but I cant see anything obvious.  Even had the guys from Head Office take a look but nothing.   Many thanks for helping.

It's weird. But nothing uncommon. You can paste the config of the 2 routers here. We will take a look. (I believe nothing is in the routers).

Is it simple like LAN---->Router1----->WAN---->Router2----->LAN type scenario?
