View 2 Replies View RelatedI have a DMZ (50) from where I need to allow some protocols to inside zone (level 0). I am doing that with ACL, but after having done that the implicit security level rule to lower level (outsite level 0) is not working anymore, I guess by the implicity deny after the acl. I'd need allow traffic to the outside zone from DMZ, as well as the inspect traffic from the inside one. Is there anyway to have both ACL and Security levels?
If not, what do I need to do to just allow some protocols going to higher level and leave the higher-to-lower traffic inspected allowed, same schema as we have with security levels.
How can I set up a network with different security levels to different groups?
View 3 Replies View RelatedI have a customer with an ASA5510. We have an SSL VPN (tunnel-based, or "SVC") that we use for remote access. That works great.They want to be able to use this same functionality, but add users who will not have the full access that the current SSL VPN users have. So in other words we currently have a small group of users who get full access to the LAN. Then they want to have a second group of users who will only have access to certain nodes.I'm wondering if there's some way to do this using LDAP between the firewall and the Radius server? The user gets put in a different tunnel group depending on what the FW learns from the server?We only have the Anyconnect Essentials license, so unfortunately we can't do a clientless SSL VPN, which otherwise might work well here.
View 3 Replies View RelatedI recently upgraded our WLC 4404 to release 7.0.98.0. The process was very smooth with no issues. The controller manages access points in two buildings. Prior to the upgrade the access points were maintaining high TX power levels...typically between 1 and 3. After the upgrade the power levels all droped to 6 and 8. I have confirmed that the correct external antenas have been set for each access point. I have not done a site survey to see if the lower power levels are acceptable. But the environment has been very consistent for the past year with regards to TX power levels. For the time being I have manually set a power level of 2 to prevent any service outages. Is there any explanation as to why the power levels have changed so drastically?
View 3 Replies View RelatedI'm trying to make a setup on my Cisco 881 router, but I'm having some trouble.I've managed to configure logging in with a Public-Private key pair over SSH, but it's also still possible to log in over SSH with just a username and password. I'd like to prevent this, if possible. I imagine I might have manually configured this to be allowed at some point, but I can't quite figure out how I did this, as no matter what I've tried to remove, it keeps allowing this option. I still need to be able to log in with a username, because I want users to have different privileges.
Once I've logged in using the Public-Private key, I don't automatically go into privilege mode, even though the user is configured with a privilege level. I'd like to configure that users that I've configured to use a certain privilege mode, automatically go into privilege mode without a password prompt. I know it did this before I started using the Public-Private key (or before I used AAA, which was configured around the same time), so I wondered if it's possible to do this still.
i have a strange issue on a link between two ASA5510: both ASAs are interconnected by a P2P Fastethernet link, and the traffic between both ASAs is being secured by a L2L IPsec tunnel. The configured MTUs are 1500, however packets bigger than 1020byte are being dropped. IOS is 8.0(5). I didn't find so far any CAVEAT describing it.
View 2 Replies View RelatedI've got tons of fibre in my network. However, tbh, my knowledge about correct light levels isn't great. I generally wait until my router complains about a light level before I do anything. I would like to set up SNMP monitoring for light levels, but I need some kind of baseline.Anyone with extensive fibre experience? What light levels should I be looking at for both multimode and singlemode fibre?

View 14 Replies View RelatedIs it possible to configure the ASA to:
log syslog informational to one host
and
log syslog critical to a different host
It seems that the ASA allows you to only specify 1 logging severity level for all syslog hosts..
In CLI we have users log in at priv 1 and use "enable" to increase privilege and do configurations. This allows "accounting" of command history. On the AIR-AP1121G-A-K9 (12.3(8)JED1) I cannot duplicate this for http login.
I can log in as a user at priv 1. When I try to go to a privileged link like "Security" I get prompted for a second login/pw. Nothing works here unless I have a second user defined at priv 15 and enter that login/pw. The problem is - that login/pw can be used to log in via http in the first place which bypasses accounting of the actual user. It also allows login to the CLI at priv 15 which I cannot permit.
username test1 secret 5 abcdxxx
username test2 privilege 15 secret 5 efghxxx

I have FWSM's in Cat 6513's. I have a need to be able to session from the switch to the FWSM by using default account (not local user), at privilege level 15 I further have a need to allow a user read only access by ssh'n into the FWSM...
I believe I need to setup a local user, at, say privilege level 5, assign the show command only to privilege level 5, then set the authorization command for that user. So, i think my command sets are as follows to accomplish this:
username <username> password <pw> priv 5
priv command level 5 mode exec command show
aaa auth ssh console LOCAL
aaa auth enable console LOCAL
aaa authorization command LOCAL
I think, that this will allow the user at privilege 5 to run only the show command and only by SSH to the FWSM while allow the priv 15 level default login to continue to function properly.
How can I achieve this. I am obviously a novice cisco user and really fight my way around. I just want to grant access to a vendor to connect to his vpn. What ports need opened and what else do I need to do?

I need hosts on 1 of these interfaces to be able to get to a specific IP and port on the other but I DON'T want to blanket enable 'same-security-traffic permit inter-interface" I have added an ACL inbound on the interface allowing the desired traffic and inbound on the other for return traffic and it simply doesn't work.

I have at the moment an ASA5510 pair in Multiple Context configured. Everything is ok, but we use til now only ACL features.Now I would be interested in configuring 2 contexts, with IPSec VPNs. One VPN per context. But I cannot find any information if it would be possible to use a shared interface for both contexts. My wish would only be to spare public IPs.If I have to configure 100 VPNs in 100 contexts, do I need 100 public IPs ?

View 6 Replies View RelatedVerifying the operation of the ASA when configured with Global access rules. Does the global rule overide the interface security levels? According to the ASA order of operations, the interface specific rule get's processed first and then the global rules, but It does not say anything about interface security levels. Observing an ASA in production that has global rules configured I see that an interface with a security level of 50 that has no rules applied to it, passing traffic to the outside interface (security level 0) drops the traffic. Syslog shows that it hits the global access rule implicit deny. Does the implicit permit any to any less secure interface not apply?
