I’m using a cisco 5510 ASA at the head office and all the branches (32) connect to the head office via cisco VPN client(Remote access VPN), as per the configuration branches used to get ip addresses from the VPN pool randomly. Now, my requirement is I need that each branch should get the same ip address every time when the VPN is established. Is this feasible?
View 3 RepliesMy wireless router [Linksys WRT54G] has recently been dropping the connection simultaneously between two desktops. I have one desktop plugged into the router with an enthernet cord, but the other is running a wireless card. I recently got a Windows notice stating that there is an IP address conflict between my two computers. I check my IP addresses using my ipaddress.com and both computers are sharing the same IP address. I also checked the connection with my smartphone and when I am connected to the internet through my wireless; it gives me the same IP address as well. So, every device I'm using through my router is giving the same IP address at my ip address.com. I'm assuming this may be what is occasionally knocking my router offline, causing me to have to reset, but it will knock both computers offline within a few minutes of resetting.
I believe that all 3 devices should have different IP addresses when connecting to the internet, so is this a setting I need to adjust in the router, and if so where do I go, or can I try to assign one of my desktop computers a new IP address? I have no idea why my smartphone would be using the same IP address when connected through the router either. I'm going to guess that the problem is with a setting within my router.
I am using a range of IPs from my inside LAN for my IPSec VPN clients. For example my inside network is 172.16.1.0/24 and I have a pool setup like this: ip local pool vpnpool 172.16.1.200-172.16.1.210 mask 255.255.255.0.
Before the upgrade to 8.4 it was working and now it isn't. Clients can connect and pickup and IP but can't cominuicate with the inside LAN. I think I have to do manual NAT to nonat this range. So I want to try the following:
object network obj-vpnpool range 172.16.1.200 172.16.1.210 nat (inside,outside) 1 source static any any destination static obj-vpnpool obj-vpnpool
However there are two things preventing me from doing this:
1) When I try to create obj-vpnpool I get an error stating that this object overlaps with local pool
2) Even if I create the obj-vpnpool with a non-overlapping range, when in the VPN config I don't have an option for selecting obj-vpnpool.
Can we assign Secondary ISP-2 Pool IP to DMZ Server, network design attached for reference.

View 3 Replies View RelatedI have my firewall on IP 192.168.0.1 (for example, real IP is a class C address). I have a web server (Ubuntu 10.04, though this happened before with an 8.04 box as well) on ip 192.168.0.101. Everything will be functioning fine, and I won't have any issues for a while. Then, randomly I'll have problems getting to my web server, getting disconnected from SSH sessions. I go to one of my linux boxes and do an "arping -b 192.168.0.101" and I will get two responses, one from my firewall and one from the box, as illustrated below. The only way to correct the issue that I've run into is to reload the firewall, which will then behave properly again until it randomly decides to start answering ARP requests on the other IP again.

I have two ASA5510's set up in failover, and the secondary keeps crashing after doing the interface checks when bringing failover up. This only happens if I try to upgrade the image on the secondary to anything newer than 8.4.1 (I've tried with 8.4.1-11 and 8.4.2). The primary one run just fine with new images.
I don't have the exact error right now, as I need to do a screen capture from console. It's just a huge crash dump.Are there anything I might have missed during the upgrade? Should I cold-boot both the firewalls in the correct order?

The unit is configured as internet gateway. 4 NAT ports are active. When firewall disabled all works fine. When firewall enabled I do get connection lost at random interval. In firewall only 4 rules added to the default 3 rules. The added rules are:

I do get at random times connection lost when navigating with windows explorer on a PC with IP 192.168.1.x to a share on a PC with IP 172.25.152.74. The same happens when copying files. Sometimes it works, later it fails or reties are needed. When the firewall is switched off all runs fine.

We have to use scp on all of our network devices. It worked quite well on our routers and switches but I can't seem to get it to work for the firewalls and IPS. I enabled scp on my ASA5510 using the command "ssh scopy enable". I also ensured that a rsa key was generated and that ssh ver 2 was enabled. But I can't seem to locate the commands to actually have my firewall either copy it's configuration to a server or reach out to a server to pull down a file. We are using IOS 8.2(1).

My device has 3 interfaces configured: inside, outside, DMZ. Right now I can access the DMZ from the Internet and I can access the DMZ from the LAN using an exempt nat statement. I am having a few issues setting up DMZ > LAN access however. The servers running on the DMZ need to send information to my LAN such as syslog traffic for example. Will DMZ traffic be NATed or should this somehow be excluded? Bascially all LAN devices should get to the DMZ devices by their actual IP and vice versa. Are there any special statements I need to add to the ASA such as nat or ACLs to make this work? My LAN is 10.10.6.0/24 and DMZ is 192.168.254.0/24.

Obviously I will be opening a TAC case to assist with the upgrade and I will also be upgrading ASDM software at the same time.

I had previously engaged cisco regarding the upgrade and they have recommended an upgrade path to ensure success. Also, I have a pair of test ASA's that I've gone through the upgrade process with - documenting the changes in commands and any changes in my config (I didn't notice any).So, the reason for my post is this: What are the gotcha's that you may have run into when upgrading your ASA's?These are fairly high visibility ASA's and any downtime due to the upgrade needs to be mitaged as much as possible.

If I move the compact flash to the external bay, all of the other lights remain the same as described above but the Flash LED goes to steady Green. How ever, there is still no response whatsoever from the console port. Have replaced the DIMM but that had no effect.
