The configuration allows only the host with the IP address 192.168.10.1 through the Ethernet 0 interface on R1. The output on the R1 table shows how the network grants access to the host. All traffic sourced from Host B destined to NetA is permitted, and all other traffic sourced from NetB destined to NetA is denied. This figure shows a select host being granted permission to access the network. Allow a Select Host to Access the Network These configuration examples use the most common IP ACLs.
If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.
This document is not restricted to specific software and hardware versions. Refer to IP Addressing and Subnetting for New Users for additional information. Prerequisites RequirementsĮnsure that you meet this requirement before you attempt this configuration: The command syntax format of a standard ACL is access-list access-list-number udp source source-wildcard ] destination destination-wildcard ]
Refer to Configuring IP Access Lists for more information on different types of ACLs supported in Cisco IOS Software and how to configure and edit ACLs. This document discusses some commonly used standard and extended ACLs. These are examples of IP ACLs that can be configured in Cisco IOS Software: If no conditions match, the router rejects the packet because of an implicit deny all clause. Because the Cisco IOS Software stops testing conditions after the first match, the order of the conditions is critical. The first match determines whether the Cisco IOS ® Software accepts or rejects the packet. The router tests packets against the conditions in the ACL one at a time. The IP ACL is a sequential collection of permit and deny conditions that apply to an IP packet. ACL criteria include:Ĭomplete these steps in order to construct an ACL as the examples in this document show: Your router examines each packet in order to determine whether to forward or drop the packet based on the criteria that you specify within the ACL. In order to filter network traffic, ACLs control whether routed packets are forwarded or blocked at the router interface. So I guess pfsense isn't at fault here.This document provides sample configurations for commonly used IP Access Control Lists (ACLs), which filter IP packets based on: Basically, I want the 2 subnets to be able to talk to each other with nothing blocked.Įdit 2: Not sure why but I added a static route in truenas (OPT subnet) and that seemed to solve the issue for that machine at least.
If anyone knows how to help fix this I would be very grateful. I also tried using LAN Net and OPT net in source and destination and the rule seems to catch the traffic but it doesn't get a reply only sent packets. I have the default allow (interface) to any rule, rule on both interfaces. But it also has an interface on the OPT subnet so idk if it's using that to get to it.
Whats odd is I have an R510 connected on both subnets and if I ping 10.0.0.12 (R510 LAN) from the OPT subnet ( 10.50.1.0/24) its reachable. But I can't ping any devices from one subnet to the other only the pfsense IP's ( 10.0.0.1 and 10.50.1.1). The OPT interface can go out to the internet just fine same with LAN. I have a WAN port, LAN port ( 10.0.0.0/24), and an OPT interface (10GFIBERLAN) as a second LAN ( 10.50.1.0).
