Is it possible to create a site-to-site ipsec vpn (lab environment) between two 5505's (ASA IOS 8.2(5) & asdm-645-206) with the same default gateway. I.E. a back to back site-to-site VPN tunnel or do I need to deploy a router and hang each 5505 off a different interface? We have plenty of public IP's but only one default gateway to our ISP (Internet).

I am struggling on a problem for over 2 weeks despite of various researches.
We have a Cisco router, then an ASA 5520 8.4(3).
The private interface of the ASA is connected to a switch, and so on connected to one interface of the router.
The private interface is as following : 129.88.63.253 255.255.248.0 (/21) =>
It is in the 129.88.56.0/21 subnet
Here is the part of the router config we are interested in :
!
interface Vlan32
ip address 129.88.63.254 255.255.248.0 (this is the tunnel default gateway configured on the ASA - 129.88.56.0/21 subnet)
ip address 129.88.71.254 255.255.255.0 secondary
ip address 129.88.75.254 255.255.252.0 secondary
ip access-group CVPN-depuis-129.88.56 in
ip access-group CVPN-vers-129.88.56 out
ip verify unicast source reachable-via rx allow-default
no ip redirects
mls rp ip
!
On the ASA, there is currently one default route for the tunneled traffic :
route Private 0.0.0.0 0.0.0.0 129.88.63.254 tunneled
As you can see, it's on the same subnet as the primary IP address of interface Vlan32 on the router.
The scenario is as following :
- we can connect to the VPN with the appropriate alias (LDAP connection), then we get an IP address in the defined range (it's a local ASA pool)
- the pool is : 129.88.71.0/24
- but, once we are connected, we can't do anything, because it seems like we don't have any network access
I'm trying to configure an IPSEC VPN + tunnel for multicast data. When the default gateway is set on the router (1841) it works fine but if I only set a route to the IPSEC peer via our gateway then the tunnel fails to come up. The end point is to a 3rd party. [code]
I found that if I add a static route for the tunnel destination via fa0/0, the public facing interface, the tunnel comes up..ip route 10.23.4.2 255. 255. 255. 255 FastEthernet0/0
and I can then ping the tunnel IP at the far end - 10.23.0.5.Why would that be? Is there a better way to do this without using a default route??
Can I have use a Gateway-to-Gateway IPSec tunnel whereby a user can surf the Internet using his local Internet connection and at the same time connect through the IPSec tunnel to a remote subnet using RVS4000 routers?

I recently got a new laptop and ever since, the internet goes in and out. Most of the time it is not out long enough to display the no connectivity icon or stop music from streaming but it is noticeable. When I run the troubleshooter it says that the default gateway is unavailable. I tried manually setting the connection information but the same thing keeps happening except the troubleshooter then says that DHCP is not enabled. I've disabled every firewall I can find and updated all the drivers available. Here is my info:[CODE]
View 3 Replies View RelatedI am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices? Is this a real solution an ASA can provide?

View 2 Replies View RelatedWe have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?
When I plug my laptop up to our modem, all i get is local access. IPconfig gives me to default gateway or dns suffix. Naturally there is no wireless. My roomates laptop runs fine wired or not and we have the same set up.Not sure what to do.

View 7 Replies View RelatedI'm really not clear about default-gateway on switch command, not the function but how its works.i have 1 multilayer switch (MLS 1) that have 2 vlan within it, vlan 2 and 100. on vlan 2 i assign ip address of 192.168.1.1 and on vlan 100 is 172.16.1.254. both vlans are up. then under that multilayer switch i added 2 more MLS (MLS 2 and MLS 3), and the links of MLS 2 and 3 to MLS 1 are trunking. and both MLS 2 and 3 have a same vlan with MLS 1. that i assign an ip address on vlan 2 in MLS 2 192.168.1.2 and i set default gateway 192.168.1.1, and i do the same to MLS 3 but the ip address of vlan 2 is 192.168.1.3i already setup the routing protocol on MLS 1 so that vlan 2 could contact vlan 100. but the fact it doesnt work at all, both MLS 2 and 3 cannot contact vlan 100 eventhough that are already have default-gateway setup, is there anything wrong with the configuration ??
View 3 Replies View RelatedWhy it makes problems to use a default route on a BGP-router (cisco 6500 with sup720 3bxl).Only a very few amount of hosts have that kind of problem and the 50% paket loss is only between this hosts. So another host has no loss to any of the affected hosts. looks for me like there is a problem in the CEF-table.The router has a BGP-fulltable. The gateway of last resort is only set for cases like a flapping BGP-route, so that the traffic is sent to a default next hop, because sometimes he knows a better route which isnt flapping.
View 1 Replies View RelatedWe have an ASA 5510, with two internet connections. One inteded for VPN l2l and the other for general users inet access.
On asa 8.04, I configured the crypto map on inteface "VPNAccess" and a static route to the L2L remote peer through VPN internet access, the default rotue was pointing the general inet router.
We bought a new firewall with 8.4.1, and now asa only tries to initiate traffic if remote peer is on the default gateway.
It ignores more specific routes (i mean longer masks) and always tries to use default gateway, but only for VPN, if I make a trace route for that peers it uses correctly the routing table.
I have RV042 on my remote network, i have problems with VPN connection , user can connect to RV042 but only inside IPs that can ping from vpn user.Is it any way to make the traffic from Rv042 will back to RV042 . maybe with nat.. in example below 192.168.5.100 is my lan IP from my DSL dhcp, and 172.27.0.20 ip on remote, traffic not back to my pc/vpn client, what i want is to translate 192.168.5.100 to RV042 LAN ip address

I rdp into our server 2008 via IP. This is a router on ip 0.1, this is forwarded to my server on IP 0.3. This server was setup with DHCP default gateway of 0.1. We added a new outside connection on IP 0.2. I was talked through the changes so that internal DHCP requests went to gateway IP 0.2 but RDP still used 0.1. I plan on getting rid of 0.1.Where is the setting to change the RDP to use default gateway of 0.2?

View 2 Replies View RelatedI've been trying to connect to the internet all day. Every time it connects, but only with limited connectivity. I run troubleshooting, but it doesn't fix the problem. Sometimes it won't have anything to report back other times it says that the default gateway is unavailable. My laptop is the only device in our home that won't connect, so I don't think it's the router.I think the router is a cisco router, there is a cisco box mounted on the ceiling with a cord leading into it (I don't have access to any buttons though)I live in an apartment building with free internet, so I'm not sure who the provider is.

View 11 Replies View RelatedI had problems connecting to my wireless internet for extended periods of time with my lease expiring almost instantly. Nobody else in my house had trouble connecting, only me. Troubleshooting the connection only showed that the default gateway was not available and failed to allow me to connect despite "fixing" the problem. I attempted the ipconfig/renew, netsh int ip reset reset.log, and netsh winsock reset catalog operations in cmd as an administrator to no avail. Finally, as a last resort, I reset my modem and that finally allowed me to connect although occasionally I would be kicked off the connection and have to restart the modem again. I would still like to know the problem and a possible solution since my friends seem to have a similar problem with their wireless internet.

I got a hand-me-down laptop the other day. Wireless (WLAN) works fine, but I can not connect via ethernet.
It gives the "Limited or no connectivity" message, even if the ethernet cable is unplugged (no "a cable has been unplugged" message)
The laptop is plugged in to an EWIRE modem/router. Desktop connects fine via ethernet, as does my PlayStation 3 console via wireless. So I don't think it has to do with the modem/router. It's a Compaq from 2005 or so. Windows XP Pro SP3.

I have a general knowledge of fixing the typical internet connection problem (obtain DNS automatically, repair connection, unplug modem for 20 seconds, etc) but I've never been this stumped before.
We have a Windows XP machine on our network that is giving us a strange problem. We have it statically configured with an IP and a default gateway address which points to a router on our network. This is the same router that nearly all of our machines point to and none of the other machines have this issue.If we open up CMD and make a ping request from an outside server (public or interal servers on other subnets) we get a 'destination host unreachable' error. We can ping the ip address of the router that is assigned as the default gateway. We can circumvent this ip address by adding a static route ('route add' from CMD) directing all traffic on the network interface to the ip of the router. Once this is done we can ping and get a response from any server both internal and external. We also tried doing a tracert (without have the static route added) to an external site by IP address. The tracert does not even show a hop for the router so it seems as if the request is never making it past the interface on the XP machine. We simply get an error saying it is unable to find the host. Interesting though it does provide us with a domain name for the ip address. So somehow it is able to reslove DNS. (We have a local DNS server on the same subnet)
