On a Cisco router, you can define all the ACLs you want. However, considernig the ones that are actually assigned to an interface (an unassigned ACL won't do anything useful), you can have one ACL per interface, per direction (in vs. out), and per protocol (for example, IPv4, IPv6, IPX, etc.). If you consider only IPv4, you can have six ACLs for the three interfaces.
It shouldn't matter which port you use unless it involves a network switch.
** The router modifies the TTL field, decrementing it by one.** The router maintains the same source and destination IP.** The router changes the source physical address to the physical address of the exit interface
To forward ports on your router just login to your router's on-line interface. Port Fowarding is used when a program (lets use FileFind [not a real program]) requests a port the router doesn't understand. Lets say that FileFind requests port 130 on your router, but your router doesn't have a port 130. It does, however, have a 128. The port forwarding tells the request to port 130 to be routed through port 128.
No a bridge will transmit all network protocols to all ports, without restriction; thus the term "Bridge." A Router in true bridge mode will do the same, unless you implement some form of route management (managed bridge / router).
When connecting two computers, use cross-over. Cross-over is required to connect the transmit and receive terminals of the two endpoints. When connecting through a router, switch or hub, use straight-through. The router, switch or hub provides the crossover.
Ethernet.
To the switch the router is just another host, so it connects with a straight Cat 5 or Cat 6 cable.
Ethernet port
You need a crossover cable to connect two routers via normal Ethernet interfaces.

Configure the router ID on both routers. Configure the R2 router interfaces for area 0. Configure a loopback interface on both routers. Configure the proper subnet masks on the router interfaces.

When applying IPv4 addresses to router interfaces on a network, you would manually configure predictable addresses. For example, the lowest or highest address of the local subnet, on each particular router interface.
It is a six port ethernet bridge with six computer capability networking.

The highest MAC address among the active interfaces of the network will be used. There will be no router ID until a loopback interface is configured. The highest IP address among the active FastEthernet interfaces that are running OSPF will be used. The highest IP address among the active interfaces will be used.
