Cisco 861 setup to use static IPs on the lan side with port forwarding
Recently I have obtained used Cisco 861 router and I would like to use it in our network. I'm completely green if it goes about professional routers by CISCO...
Anyway: It will connect the ISP to our 24 ports switch. It needs to have static IP for itself and also should give static, predefined IPs to the machines (or rather accept IPs from the computers connected to it with custom IPs form the 192.168.2.xxx pool) For certain IPs I also need to forward ports from outside ports (the ISP) to the inside ports (on the lan side, I presume it is the NAT thing, right?). How should I program the router using console or CCP? Which is simpler?
I enclose my initial config which works with the University DHCP-provided IP and DNS (this will be changed later during the router deployment)
Current configuration : 3647 bytes

Re: Cisco 861 setup to use static IPs on the lan side with port
Thank you. What about port forwarding? Say, I have 3 computers connected to the switch which will be connected to one of the Vlan1 ports with ip 192.168.2.254 (which are ports fa0-fa3).
192.168.2.110 Internal port 22 external port 8670
192.168.2.111 Internal port 22 external port 8680
192.168.2.112 Internal port 750 external port 8690
How to set up NAT for this to work? Only those computers will require port forwarding.
And also: I don't want to use internal DHCP. I want for any computer connected to the switch with IP configured by the user (under condition that it will be from the 192.168.2.0 pool) to be able to connect through to the internet.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
