Mar 1, 2012We have a user who needs to access a vpn from his MAC through an ASA 5505. The user is getting an IP via DHCP and the outside interface of the ASA gets it's address via DHCP as well. The user states that when he is home or anywhere else but behind the ASA it connects fine, but once the ASA is added it times out. He is able to get to the internet from the machine without any issues. Looking over the config on the firewall it isn't set to deny any traffic and there is a global set on the interface and it is nat the inside interface. There is no global policy in place so I was considering implementing the following:

Cisco Firewall :: ASA 5505 Blocks New Connections To IP
May 22, 2012I am trying to get up to speed on this topic as quickly as possible.
Here is my issue:
1) We are able to access the webiste
2) We are able to upload data packets
3) We allow the website to time out while we are uploading data packets
4) When we attempt to re-access the website the ip is blocked a) this includes pinging and trace
5) After an undertermined period of time the ip is unblocked and we are allowed to access it again.
The ASA 5505 router is the last forward facing stop before entering the VPN tunnel. We have tested by circumventing the ASA and we are unable to duplicate the disconnect. We have reviewed the config file and have not been able to identify what rule/settings could be affecting this.
when tracing port usage, the actions use 2 tcp ports and 1 udp port, the 2 tcp ports open and close by each transaction, when the ip block occures the 2 tcp ports are "dead" the udp port remains open (appearhently sending the remainder of the data packets)

May 16, 2013I have an ASA 5505 with Security Bundle license.
I am able to create 2 LAN networks (192.168.9.0 and 172.16.9.0) Vlan1 and Vlan12 respectively. I also setup 2 outside interfaces (outside1 and outside2).
Network 1 (192.168.9.0 - VLAN1) has no issues going out via Outside1, however I can't get Network 2 (172.16.9.0 - VLAN 12) to go thru outside2.
I put in a static route (route outside 172.16.9.0 255.255.255.0 x.x.x.x), the x.x.x.x is the default gateway of my ISP.
Cisco Firewall :: ASA 5505 Stops Accepting Connections
Nov 21, 2012 A client has an ASA 5505 with a base license. The version information and configuration is attached. In 8 hours, sometimes less and infrequently more, it becomes inaccessible. All connections are dropped and the only way to access the device is through a console connection. The WAN interface (VLAN 3) is connected to Verizon FIOS. The interface was set to 100 MBps and full duplex, but I just changed it to auto on both the speed and duplex to see what would happen. The LAN interface (VLAN 1) is also set to 100 MBps and full duplex It has not been changed.
The last time it happened logging was running, but nothing in the log indicated a problem. In fact, the last log entry was a couple of hours before the lockup (there's little or no traffic on the ASA while the problem is being diagnosed).
Cisco Firewall :: ASA 5505 - Dropping TCP Connections On Inside Interface
Feb 12, 2013Trying to add inside routes on an ASA 5505 to point traffic to another gateway for other connected networks is resulting in the following error 6Sep 16200 819:13:5810601510.184.236.1265003810.170.54.1823389Deny TCP (no connection) from 10.184.236.126/50038 to 10.170.54.182/3389 flags RST on interface insideI believe the problem is due to the Asymetric tcp connection and the ASA is dropping the connection because it only see one half of the traffic.Is there a way we can stop the firewall dropping the TCP connections on the inside interface? i've tried removing the threat managment which didnt work.Annoying thing is were putting the ASA 5505's in to replace old Watchguard soho firewalls only the watchguards forwarded the traffic no problem at all.
View 1 Replies View RelatedCisco Firewall :: 5505 High Availability Over Dual WAN Connections
Mar 20, 2011One of my remote sites acquires Internet connectivity via a cable modem service. This goes down intermittently, of course. I would like to purchase DSL service from the local telco and configure the edge ASA (currently a 5505) to use the cable modem path normally ... and fall back to the DSL path if necessary.
These seems hard to do. The edge box would need to evaluate the viability of a WAN path using some set of tests ... perhaps pings to a handful of major Internet sites. If all those pings start failing, it would stall for a minute, to give the WAN service provider time to recover ... then cut over to the second path. Cutting to the second path might mean pushing new DNS server addresses to clients (or perhaps the edge box would hand out both sets of DNS servers all the time and rely on the clients to try them all.) Once the cable modem provider restored service, the edge box would stall for a while (ten minutes? an hour?) and then cut back.
I'm willing to replace the edge box with something fancier (a bigger ASA or something sold as a router or whatever), although I'd like to stay under 10K (list) for such a replacement.
Cisco Routers :: ASA 5505 - SMB Wireless Router That Supports Full Tunneling Over L2l VPN?
Feb 7, 2012I'm looking for a device which will allow me to forward all internet bound traffic through a L2L IPSec tunnel from branches to a central hub and internet connection.
I've recently purchased a RV120W(as a test branch device) which i've tried to get working with the ASA5505 at the central site. I can get the VPN to come up but can't manage to get the internet bound traffic through it. Reading up on the issue, it looks like full tunneling or IPsec wildcard forwarding isn't supported on the RV120W and RV220W devices [URL] The source mentions that the RV0xx series supports this feature, however one of my requirements is wireless on the device.
Any device which supports this rather than just the standard split tunneling, alternatively a workaround which will allow me to use RV120Ws at branch sites? Would an SRP521 support what i'm trying to achieve?

May 14, 2012We are planing on offering low end ASA 5505s as a customer offer to connect their network to our cloud as this is a business requirment. However, one of my colleagues is convinced that the license for the 5505 is *not* based ont he number of IPSEC endpoints, but the number of distince connections via *any* tunnel. So, according to him, if you have a license for 10 IPSEC endpoints, if you have 11 people connecting via *one* tunnel from a customer's network to our cloud, you go beyond your license.

we are running a Postfix MTA behind a IOS Firewall (ZBF) on a CISCO1921. Sometimes we get more than 2000 smtp login attemps like

Aug 1, 2011We are in the process of getting two new connections pulled in that I would like to utilize in the following configuration.
DS3 - 45/45 I would like to use this circuit for all of our servers to NAT out of as well as our VPN tunnel to our remote site. It will be much more reliable than our cable line.
Cable Internet - 50/10 I would like to use this for all internet traffic that users generate. I would like to be able to fail over to the DS3 if this line goes down.
To get all traffic go out the cable line would take a dynamic NAT rule and a default route. How would I automate a failover to the DS3 with a backup route and dynamic NAT rule?
I understand that if the DS3 goes down it will take manual intervention to bring the tunnel back up and servers with static NAT will need reconfiguration.

When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.
