Why does Cisco recommend a configuration of originate-only on the ASA with multiple peers configured and the answer-only to the other end? Shouldn't it work as Bi-Directional ?
[URL]
The only scenario I see which could break is if both peers try to establish a VPN at the same time to the ASA. Is there any other reason ?
I have 2 ASA 5505 Firewall, I Configured Site 2 Site VPN no both the fitrewall, as i have a dual ISP, i am able to create the tunnel with primary but once my primary is down i am not able to create the tunnel with back up ISP. During the troobleshoothing by typing Show isakmp sa and Show ipsec sa, i can see my tunnel is up, but not able to decap the packets.
As it will look like
#pkts encaps: 15, #pkts encrypt: 15, #pkts digest: 15 #pkts decaps: 0, #pkts decrypt: 0, #pkts verify: 0 #pkts compressed: 0, #pkts decompressed: 0 #pkts not compressed: 15, #pkts comp failed: 0, #pkts decomp failed: 0 #pre-frag successes: 0, #pre-frag failures: 0, #fragments created: 0 #PMTUs sent: 0, #PMTUs rcvd: 0, #decapsulated frgs needing reassembly: 0 #send errors: 0, #recv errors: 0
I am working on wi-fi networks (ISP), So I need to block the peer to peer on my network.My network involves cisco switch 2950/2960, cisco 2800 routers and Access Points, config for peer to peer blocking, for this where I need to config either switches or router.My network basic setup is, The internet will pass from router to switch and then Access Points.

I see that Application protection - blocking peer-to-peer file sharing traffic is a capability of Cisco IOS Firewall. How do i configure my Cisco 2911 ISR to block peer-to-peer file sharing traffic?

View 3 Replies View RelatedI bought my WAG320N, I too have the internet drop out and from reading in here is a very common problem. Cisco really should bring out a new firmware version and address this issue. Any way you can block peer to peer file sharing with the WAG320N? If so how do you go about it?

1. when using the debug command it shows how it works digit-by-digit till it match a pattern
2. It says in the study guide ( If a match is found, the router immediately processes the call - chapter 6) so I understand its not en bloc
We are having an issue with BGP flapping peer. We have a ASR1002 as Route Reflector and it work fine with all peers except with 2 peers.

View 2 Replies View Relatedam in the progess of replacing a Zyxel USG 300 to a Cisoa ASA 5510.In the Zyxel I have some Site to Site, where the peer is a dyndns.org adresse, becourse the peer is a dynamic ip-adress.
I have maybe 10 site to site´s where the peer is a dynamic with a dyndns.org adress, and the presharedkey is diffrent at each tunnel.How can i make this configuration at the ASA 5510?
I have another odd issue (I get those alot) I have an asterisk box that moves around between 2 IPs, thus the dial-peers are unpredictable as to their target IP. They work as the dial-peer will eventually (after 1 min) time out and go to the other dial peer, but waiting 1 min sucks, and it's a tiny network, 5-10 sec would be WAY more than enouph. Does anyone know off hand a way to get them to time out faster?
View 5 Replies View RelatedI have a simple question regarding dead peer detection on the ASA 5520. I am using a cellular VPN device to connect back to an ASA 5520 and I have noticed that the connection drops at random periods during the day. The vendor for the cellular device recommends disabling dead peer detection on their device, which I have done. The question is, where is this disabled on the ASA? is it the IKE Keepalive setting under the tunnel group option?

All 5505 are connecting to 5545.Can I configure the ASA for a site to site to automactically discover the the peer address and automatically establish a connection with 5545?In other words can I configure all settings for the site to site except the peer address. Once connected on network and get outside DHCP, can it also put that address is the peer section of site to site?

I'm trying to connect a 2nd ASA, but I've noticed I can only add 1 cryptomap to the outside interface. A show ver shows 1 Virtual Private Network Module... Surely that doesn't mean only 1 VPN?Do I use one crypto map, and add a second 'set peer' & 'match address' inside the crypto map itself?

View 3 Replies View RelatedWe are trying to add an additional LAN-to-LAN IPsec VPN to our network. We currently have one remote office connected, when we configure the second VPN matching the first the tunnel never begins to establish. There is an ACL that is dening the static IP for our remote office.
The layout is as follows:
Main office = ASA 5520
Remote Office A = ASA (Unknown Model)
Remote Office B = Adtran Router
All devices have static IP addresses.
We used the ASDM VPN wizard to create both VPN's.
We have created a rule allowing all traffic from our remote office IP, and that had no effect on the VPN aside from eliminating the following message from our logging:
4 Mar 19 2012 15:18:01 106023 67.50.19.230 50234 TWT-hq-e 31326 Deny udp src TWT-outside:67.50.19.230/50234 dst inside:TWT-hq-e/31326 by access-group "outside-in" [0x0, 0x0]
We have verified that both sides are configured the same however the VPN never is initiated so as of right now the ASA is simply blocking all attempts from our remote office to connect.
We have a Cisco 3845 router for Site 2 Site VPN tunnels to external business partners. The IOS is (C3845-ADVIPSERVICESK9-M), Version 12.4(15)T8.One of our partners is doing a DR test and needs to have us swing the VPN traffic to another peer in a test location temporarily. I plan on adding the test hosts to our existing encryption ACL, but instead of building another crypto map, I was wondering if I can add a secondary peer to the existing one?
View 3 Replies View RelatedI've been using an ASA 5505 -- ASA 9.1(1) -- with an IPSec Remote Access VPN. Everything works properly, though I recently noticed that when my IPSec session is disconnected, I get the standard message ID 113019, but within that message the Peer IP address is incorrect. In fact, it isn't even close to my actual remote address. [code]
When I first researched the IP, I found it coming from China, which freaked me out. I changed settings, rolled back to 9.0(1), and nothing worked. Finally I rebooted, reconnected the VPN, and the IP changed. This time it was an address from RIPE NIC. I rebooted again, now an address from ARIN in the USA. One more reboot, now a random Comcast residential address.
Within that boot cycle, the peer address always stays the same. I've connected from different devices, different IPs, different ISPs - nothing matters. Additionally, there are no firewall logs for these IP addresses at all.
ASA Remote Access VPN peer addresses in disconnect message are incorrect and change at reboot.
