View 2 Replies View RelatedI am managing a firewall setup with some ASA 5510's.One of the rules I have in the ACL list is to allow or deny (By disabling the rule) access to certain subnets.
I have a 3rd party vendor that from time to time need access to specific servers in the infrastructure, but I want to keep a certain level of control when they can access them and especially when they can not.
I know it works fine, I have done several tests to verify when they can connect and when they can not. But, now comes the tricky part, if they are already connected (Remote desktop) to the system, and I disable the rule, they are STILL!!! connected. It seems the firewall does not terminate the active session / cconnection when I disable the rule allowing them access..

the intent of the above is that management connections will only be accepted via SSH, and all of those will be authenticated via RADIUS, unless it's down, then it will use the local username/pw combinations, most of which are given Privledge level 15. Telnet should never work.SSH works as expected (authenticates via RADIUS), but the problem is that Telnet also works, will ONLY use the local database (never RADIUS), and, for some reason, leaves the users at Privledge level 1, instead of the configured 15.Essentially, it seems that at every point I have told it to do something that isn't the default with regards to telnet, it ignores me.Prior to a recent IOS upgrade, the switch didn't support SSH, so the previous config was Telnet with RADIUS, and that worked fine.

View 12 Replies View RelatedI have 3 ASA 5510s; two of which are in production and the 3rd one is new. I inherited the two in production and was trying to configure that 3rd one using some of the existing object-group network statements. The problem is that when I try to create a range of IPs in one of the object-groups; the range command is not available. Here is one of the statements extracted from one of the production ASAs: object network REMOTE range 62.77.130.14 62.77.130.208.Both ASAs have the same image ver (asa842-k8). Is there something that I am missing to be able to enable the range option on the new ASA?

I do it but remote users (connected with ipsec vpn cisco client) could access remote LAN but when they try to navigate through internet, there's no ip connection.
Do I have to configure some NAT ? I've already configure some rules to let the vpn ip pool go to the internet.I just want my remote users to navigate on internet through the vpn tunnel and the remote gateway (the asa).Do I have to setup some proxy ?

I have a cisco asa 5520. i need to forward telnet to a router on the inside interface. Here is what i have done so far but it doesnt seem to be working.
I have created an access-list that looks like this:
access-list 102 extended permit tcp any host 10.10.60.2 eq telnet
But when do this it still doesnt forward my request to the router at 10.10.60.2 . So just to explain what im trying to do. I use Putty, i am putting the outside interface IP into putty, selecting telnet and opening the session. i need the outside interface to see this request and know to forward port 23 to the router on the inside interface with IP 10.10.60.2. The ASA is running version: asa842-k8.bin
I got 2 x 5520 ASAs configured in active/standby mode and they are connected to 2 x 4500 switches in which too configured for failover.Telnet to ASAs is allowed only via subnet 172.18.0.0./24
I can only ping and telnet to the active ASA from subnet 172.18.0.0./24 but not the standby But i can ping and telnet to both the active and standby ASAs within the 4500 switches.
I am having some troubles finding information about how to configure firewall policies (rules, chains, etc.) via telnet on a RV016. The reason for that is that i keep getting some log entries "connection refused - policy violation" and "blocked" even with my firewall wide open (only allow rules on all interfaces, SPI and block wan request disabled, multicast and https enabled, etc.... ). Also, with these exact same rules, i can only connect via PPTP with the firewall disabled. The minute i tick the enable option the tunnel never gets to authentication phase. I then started reading OpenRG manual and many things are quite similar, but some other entries are missing from that manual (maybe some changes made by cisco?). I am trying to figure out some service ids, chains (e.g. the rv016 has some rules redirecting to chains 10, 100, 200 but i can not find them anywhere), and so on. I have only one rv016 and about 60 connections to it so i can not experiment that much without having the whole company on my neck with internet problems.

View 2 Replies View RelatedDo you now if it is possible to disable the xlate for some connection?
The ASA has some concurrent session limitation that, I think, is related to xlate connections.
As my firewall is not performing any kind of NAT, is it possible to disabe xlate for some connections.
I saw some options like nat exemption, but i not sure if the xlate still being create even if we don't have a NAT translation.
