Overlaps With Gigabitethernet0/0
answers are voted up and rise to the top Overlapping serial interfaces? (Packet Tracer) [closed] up vote 1 down vote favorite Today I tried configuring some practice assignments at home, with packet tracer. But whenever I try to configure and activate the serial interfaces it responds with "198.162.10.0 overlaps with Serial0/0/1" or Serial0/0/0. To make it easier to understand I will give the IP Addressing table: what does ip address overlap mean R1: FA0/1:- 160.24.65.1 - 255.255.255.0 S0/0/0: - 198.162.10.1 - 255.255.255.0 S0/0/1: - 198.162.10.9 - 255.255.255.0 R2: S0/0/0: - 198.162.10.2 - 255.255.255.0 S0/0/1: - 198.162.10.5 - 255.255.255.0 R3: FA0/1: - 160.24.65.65 - 255.255.255.0 S0/0/0: - 198.162.10.10 - 255.255.255.0 S0/0/1: - 198.162.10.6 - 255.255.255.0 What am I doing wrong? To the ones who answered, thank you for helping me, but it was not quite what I was after. You see I have to use the 198.162.10.0/24 network for serial links, and 160.24.65.0/24 for local networks. So switching masks might solve it but not within the "rules" of this. To further explain I will put the whole addressing table here: ![enter image description here][1] The topology for the addressing for those who are interested: ![enter image description here][2] Example of a working one with similar networks. ![enter image description here][3] cisco subnet share|improve this question edited Jan 19 '15 at 21:17 asked Jan 19 '15 at 10:42 user13453 closed as off-topic by Mike Pennington Jan 19 '15 at 21:34 This question appears to be off-topic.

What's the mask associated with the ip address assigned to Fa 0/0? I don't think so. He is trying trying to put the 172.16 network on both interfaces.

In order for this to work, you could use something like a /20 which is 255.255.240.0 A /24 would do too: 255.255.255.0 Quote lon21 Senior Member Join Date May 2011 Posts 201 Certifications Computer Science and Network Computing BSc, CCNA 06-12-201108:32 PM #5 Originally Posted by jwashington1981 We need more information to be able to answer that.

I have a Router (Lab A) Which connects to a pc via fa 0/0 with the ip address of 172.16.10.1 I also have a serial links which connects to a router which should have the ip of 172.16.20.1.

You can only forward one of each port to a different machine on your network. You can't forward 25565 to your new laptop, while also forwarding port 25565 to that awesome computer... You can only forward one port to one computer Could you show us a screen shot of your current port forwarding settings? What have you already defined/Set up under your port forwarding options? Do you have a DMZ enabled? What Operating system is the server running on? Have you messed with any of your system's firewalls yet? If you want to set up two servers within the same network, it's definitely possible, however you'll have to tell us up front if that's what you're trying to do here. Remember, the more information you give us about your problem, the more we can help you!
