In general, if someone encounters, then you can try to solve this problem in this way. Although everything is possible here Depends on the emulated image. In the current version I had no problems working with 3725, but there is information that the problem persists since 3745.
Cisco asa ios for gns3 series#
This bug was observed in older versions of GNS3 on some IOS images, in particular when working with 3700 series routers. Therefore, be careful, you must change these ports when adding a router.īug number 3.Router configuration is not saved after turning GNS3 off and on. And GNS3 uses ports starting from 2000 as console ports for routers by default. Because On the machine where GNS3 was launched, Cisco ACS4.2 was installed, then the ports 2000-2002 were listened directly to ACS itself. Otherwise, the connection was not established, the devices did not see each other.īug number 2.In general, this is not a bug, but a feature of the basic GNS3 settings. The need to reboot the Cisco ASA after setting the basic configuration in case the switching was carried out after the device started. Perhaps the word “bug” does not quite correctly reflect the difficulties and errors that occurred during emulation, but for the sake of unity of classification I will use it.īug number 1. However, already at this stage a number of auxiliary bugs appeared. And in general, looking ahead, I’ll say that only routed / single modes work more or less fully in GNS3 at the moment. Be careful.Īctually, with the tasks listed in WB1 INE, there were no problems emulating the Cisco ASA. The command line interface is slightly different from Cisco Catalyst switches. The list of unsupported L2 functions when using the NM-16ESW module is given on the official website. In cases where there was a need for a managed switch, the Cisco 3725 router with the NM-16ESW module was used. In the first test, the firewall (hereinafter referred to as the ME) of the Cisco ASA started in routed and single modes (without support for virtual contexts).Īs part of these checks, the operation of dynamic routing protocols (RIP, OSPF, EIGRP), redistribution, IP SLA tracking was checked.

The description of how to launch Cisco ASA in GNS3 can be found at the links in English, and even in Russian. I will omit the tasks and a description of the technologies being tested, I will leave only the results.
Test topologies and test methods were taken from the first Internetwork Expert (INE) workbook (WB) to prepare for CCIE Security. FTP, TFTP, syslog server based on 3CDaemon.

I hope that this article will help you decide whether to emulate a particular topology in GNS3, and also save time when debugging your solution in a virtual environment. The article provides test results and conclusions on how fully this functionality is supported when virtualizing this device in GNS3. This device is a multifunctional firewall, can operate in various modes (routed / transparent single / multiple context), used in fault-tolerant configurations (active / standby active / active), etc. Recent versions of GNS3 have the ability to emulate a device such as the Cisco ASA. More than one article has been devoted to the GNS3 emulator on the hub, and I think that many who work with Cisco equipment were faced with the need to run network equipment in a virtual environment to check topologies and solutions of interest, when debugging idle configurations, or just in preparation for certification or the study of a particular technology.
