Cisco VPN :: Unable To Access Internet Using VRF-lite On Through ASA 5505
May 4, 2012
I am trying to “build up” a small home-network and using some of following Cisco equipment’s
ASA 5505 v8.4.3 witch base licenseCisco Catalyst 3750G with ipservices version 15.0.xand 1 qty of AP1142N I am not able to get internet access from any VRF’s.
From "MILAN (LAN) VRF, I am able to ping my gw: 10.45.45.1 but I am not able to ping for example: “linknett VRF”.
It seems that i am missing some NAT rules on ASA or ?
If i connect my laptop directly to the ASA, i am able to get internet access!
I am not feeling comfortable with a new ASA 8.4 code yet, so im not so sure which exact code's i am missing on ASA ...
attached digram including configuration files from ASA and 3750 sw.
I have an ASA 5505 which is unable to acces the internet, even when reloading just the basic config.If i setup my laptop with the outside ip or another ip in the subnet, it does work.
I have config ASA 5505 and it is conencted to layer 3 switch that connects to cable Modem.
ASA is config with DHCP option and PC is able to get the IP from ASA. But from PC i am unable to access the internet. From ASA itself i am able to ping the Websites fine.
ASA has config with DHCP for inside and also it is doing NAT.
When i connect the ASA directly to Cable modem then pc is able to access the internet.
User A --- router A (122, fortigate 80c) --- (Site to Site VPN between fortigate & cisco asa) --- router B (93, cisco Asa 5505{in front asa got cisco800[81] before to internet} ) --- User B
After using wizard to configure the site to site VPN, the site-to-site tunnel is up.
Ping is unsuccessful from user A to user B
Ping is successful from user B to user A, data is accessable
After done the packet tracer from user A to user B,
Result : Flow-lookup Action : allow Info: Found no matching flow, creating a new flow Route-lookup Action : allow Info : 192.168.5.203 255.255.255.255 identity
I have a ASA 5505 that I have been using to test run the IPSec VPN connection after studying the different configs and running through the ASDM I keep getting the same issue that I can't receive any traffic.
The company LAN is on a 10.8.0.0 255.255.0.0 network, I have placed the VPN clients in 192.168.10.0 255.255.255.0 network, the 192 clients can't talk to the 10.8 network.
On the Cisco VPN client I can see lots of sent packets but none received.
I think it could be to do with the NAT but from the examples I have seen I believe it should work.
I have attached the complete running-config, as I could well have missed something.
FWBKH(config)# show running-config : Saved : ASA Version 8.2(2)
I am working on a site that has recently added a new subnet and I am unable to ping any of the stations on this new network. I have configured an Exempt NAT rule just the same as the rules allowing access to other networks. I have a feeling the problem is in the Site-to-Site VPN configuration since the new subnet is at the primary location over the VPN.
In the site-to-site configuration I added the new subnet to the list of "Remote Networks" and I still can't communicate with any of the devices on the network. If I go to the main site I have no problems so it appears to be related to the VPN or a configuration in the ASA on that site.
A port scan shows that all the traffic is "filtered" so somewhere either the site ASA or the main ASA is blocking the traffic.
I have a Cisco ASA 5505, with basic 50 license, that is connected directly to the Cable Modem with a public IP. I have VPN configured and active on the Outside interface. When we connect, we connect just fine with no errors, but we are not able to access any resources on the remote network.
ASA IOS version 8.2(5) Remote Network IP: 10.0.0.0/24 VPN IP Pool: 192.168.102.10 - 25
I have a 2960 SI lan lite switch that I am configuring for admin and guest access. I have wireless AP's plugged into trunked ports 2 and 3. I am using two vlan's (in addition to the native VLAN). Vlan 5 for Admin and Vlan 10 for guest access. I have ACL configured on the router preventing guest users from accessing the Admin network. I want to prevent those on the guest network from seeing other hosts in the vlan however the lan lite software does not support port ACL's. Any way to accomplish this with this switch.

I am having issue with network connectivity between remote access (RA) VPN users and remote site VPN hosts.
Topology is: RA VPN laptop (192.168.200.3 /24) ---- internet ---- Head Office (ASA5505) -- LAN subnet 10.0.0.0 /24
SiteB (10.0.10.0 /24) ---- internet ----- Head Office (ASA5505) ---- LAN subnet 10.0.0.0 /24
From head office there is no issue communicating with RA VPN and siteB hosts but Site B hosts and RA VPN users can not communicate each other totally (ping failed too).
Site B is using Cisco 867 router with IPSEC VPN to the ASA5505 at head office. I have added the ACL on this router to access 192.168.200.x /24 for VPN traffic and exempt from NATing. When I enabled ' drop log' in the class-map in the Zone based firewall config, I could not see any ping packt comes in so I believe the issue is at ASA5505 config.
At ASA5505 I use split VPN tunnel ACL and have included the subnet for 10.0.10.0/24 as well as 192.168.200.0 /24. This split tunnel ACL are applied to both the IPSec VPN tunnel and also the RA VPN group policy. The ASA is using sw version 151-4.M5.
I have a issue that i am at a loss as how to solve it. I have an ASA 5505 as my firewall. I have users from other companies who visit from time to time and are unable to use their outlook email to send messages. They can however receive messages without a problem. I also have a situation where users who use windows live to access gmail are unable to send messages.
I have narrowed it down to the fact that these uses are using ssl/tls to send the mails. I did some research and found out about the inspect esmtp setting in the ASA. I have disabled it and i still have to problem. I have also removed all outbound deny statements and still no luck.
Of note is that i can send emails without attachments. They take a long time to go out ( from minutes to hours) but eventually they do. Emails with attachments of even 10k do not go at all.
I was running image 8.2.3 and i downgraded to 8.0.5...still did not work...i upgraded to 8.4.3...still did not work. I am now back at 8.2.3.
My Firewall config is attached. I am at my wits end as to what else to try. The company has not renewed support for the device so i am on my own here!
I am using two firewalls to connect two different offices. Firewall 5510 is running ASDM 6.3 and 5505 is running ASDM 6.2, Problem is that even after connecting two sites, i am unable to ping remote network from either side. I am mentioned static route as tunneled.
I have setup 5505 ASA for Testing purposes. It has static route to layer 3 switch on outside interface that goes to the internet.
ciscoasa# sh route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
I found a tricky task for our ASA 5505 firewall. I am not able to go internet when using DHCP but I can access by using fixed IP address in client PC.Same IP, Same Mask, Same DNS, Same Gateway. All the same but no hope. Any configuration i missed in firewall?
I'm unable to have any internet connection for my new setup.
here's the overview.
Current setup is
Internet -> Router -> PIX 501 -> Switch -> clients
Internet -> static ip given is 210.193.34.1 - 210.193.34.6 Router -> Static ip assigned for NAT/External is 210.193.34.1, Local ip is 192.168.1.246 PIX 501 setting -> IP to Router, According to router screen is 210.193.34.2, but not sure what settings are done in the PIX itself as I'm unable to access it.
local ip is 192.168.1.1 Clients - > 192.168.1.0
Old setup is working fine and connected to internet. for the new setup, as i do not want any downtime for the old setup. As you can see, there are two firewalls connected concurrently to the router. I've configured it this way.
Internet -> Router -> ASA 5505 -> Switch -> clients
ASA 5505 setting -> IP to Router NAT/External/ Outside Interface, 210.193.34.6 (Or do i set as 192.168.1.0?), local ip/ Inside Interface is 192.168.2.1 Clients - > 192.168.2.0
some setup details. security policy, NAT, set to default. routing is route outside 0.0.0.0 0.0.0.0 210193.34.6
I'm unable to access after a week of troubleshooting.
We have a client that has a Cisco 1801W Firewall that is setup as a site to site VPN terminating to a Cisco ASA 5505. The tunnel is up and established, I can ping from both sides of the tunnel.
The problem is the clients behind the Cisco ASA (192.168.2.x) cannot reach certain ports behind the Router (192.168.1.x). The main thing we're trying to do is browse via UNC path (ex: \192.168.1.120 from a 192.168.2.x machine).
I got 3389 working after I changed the - ip nat inside source static tcp 192.168.1.120 3389 y.y.x.x 3389 route-map DM_RMAP_1 extendable Modified the command to include the public IP instead of interface FastEthernet0
I believe it has something to do with the way NAT and route-maps are setup currently but I'm not familar enough with them to make the changes. I worked with Cisco to ensure the VPN tunnel was fine and it's something security related on the Router.
Here is the configuration (removed a few lines not necessary. y.y.x.x = WAN IP of Router x.x.y.y = WAN IP of ASA).
Building configuration...
Current configuration : 23648 bytes ! version 12.4 no service pad
I have a 5505 that i setup with a comcast cable modem (1 static address) and i cant seem to get to the internet. Im thinking it is a NAT rule but i don't have enough experience to figure it out.The current setup is E0/0 plugged into the cable modem, and a laptop plugged into E0/7. I have assigned my laptop an address within Vlan 1.[CODE]
I have configured Site-to-Site IPSec VPN and it works. Our clients have access to inside network and Internet ("hairpinning").How can I configure access to Internet on remote networks clients if VPN tunnel fail?Remote devices is ASA5505 and Cisco 861.When VPN works i have access to Internet over central office gateway.In case when VPN fail i need still have access to Internet over local (remote device) gateway.
How do I configure Cisco ASA 5505 (using ASDM 5.2) to block a workstation (IP address) from accessing internet completely? I was trying to set up a new incoming access rule for outside interface to deny any IP traffic to that workstation but it doesn't work from some reason - the workstation can still access the internet. The ASA has no special settings, only a few ports opened for servers?
I would like to restrict Internet traffic (HTTP & HTTPS) for Inside Users with an ASA 5505. I would like to setup a proxy-like system where a User/Password must be entered before the User can actually browse the web.
I know that this can be done with an additional RADIUS/TACACS+ Server. Is this also possible without any external AAA Server, so with User/PW stored on the ASA locally only?
I have configured the ASA 5505 for internet access and outside users to use two servers in the DMZ. Every thing is working fine. When I was configure VPN, I did some mistake I guess, now inside users are not able to access internet. They get an error 405. Thats an error. The request method XXX is inappropriate for the URL /. Thats all we know. Even I am not able to access the server in the DMZ from outside and I get an error : Bad Request - Invalid HeaderThese things just happend after I did some thing on the ASA. I copy and pasted the my old configuration but still insider users are not able to connect to internet and from outside I am not ableto connect to server. The weired thing is that I can user VPN with out any issues. I can connect to vpn but I cant access any internal resources. Even inside users are able to ping internet addresses with out any issue.
i am looking for the best practices when using a Cisco ASA 5505 to provide NAT and protect my inside network from the outside.
I have the inside security level set to 100 and the outside set to 0, want other features can be used to protect the network from the Internet, am assuming that the security levels will ensure no traffic comes from the outside to the inside unless there is a rule that allows it.
Would any firewall policies be required to increase the level of security?
I have configured and tested an ASA-5505 that will be deployed at a customer's home. The ISP cable modem will connect to the E0 (outside) interface of the ASA. All other interfaces on the ASA are configured for the inside network 192.168.5.0/24. I have created a VPN site-to-site tunnel between this ASA and the UC540 to allow 192.168.5.0/24 subnet access to the internal networks on the UC540.
The user has requested that all the network devices used by the rest of the family will only need to connect to the Internet. They will not need access to the VPN tunnel and they will not need access to the computers on the 192.168.5.0/24 inside network. I was planning on performing the following tasks to get this to work.
What should i do on my Cisco ASA 5505 firewall to grant access to my network systems to access internet via gateway. I use ASDM to configure the firewall.
I have a wireless Airport Extreme on Vlan3. My problem is that I can't get internet access from a wireless client which connects to the Airport which is on the DMZ. From my laptop which is connected to the Airport, I can ping the 5505. That's as far as I get.
asa5505(config)# sh running-config : Saved : ASA Version 8.4(2) ! hostname asa5505 enable password ArKd0aXL.wihdyE3 encrypted passwd ArKd0aXL.wihdyE3 encrypted names
i have a asa5505 and sf300-48,in the sf300 have ip defult-gateway 192.168.1.93 and have internet in vlan2 but vlan 3 not work. ping from "vlan3" to "vlan2" its ok.
ASA 5505 and DMZ and Base License,"For example, you have one VLAN assigned to the outside for Internet access, one VLAN assigned to an inside business network, and a third VLAN assigned to your home network. The home network does not need to access the business network, so you can use the no forward interface command on the home VLAN; the business network can access the home network, but the home network cannot access the business network." Page 6-17.
This is exactly what I need. Mail server in DMZ, full access from internet to DMZ, and from inside network to DMZ, no access from DZM to inside network. If I good understand, this is possible with base license.
I successfully configure, internet Access for DZM and inside network, Mail server can be accessed from internet, as well as RDP on inside network. But I have problem to configure communication from inside network to DMZ. [code]
Ok so I am accessing the Internet by LAN cable hooked up to the (LAN slots?) on the motherboard.After a lightning strike, where there was once 2 yellow lights is now gone.Question is what needs to be replaced because the slots are on the mobo itself.
