Need Configuration Assistance - Can't Seem to Get the VPN Working

I have a Hub Router that is configured to be the primary DMVPN that talks to other spoke routers. I was able to get the tunnel working from the Hub to the Spoke and vice versa. The fix was adding a static route to point to the tunnel interface. Would it be possible to make configuration changes on the primary DMVPN router only instead of making changes to all of my spoke routers? Also, from the spoke routers if I change the static route to point to the tunnel interface would they be able to communicate to access the internet as well?

I spoke to Cisco TAC and they told me that I should be able to make changes on the Primary DMVPN router and not make any changes on the spoke routers, however I didn't get a response from them yet.

chunjo

ASKER

I know if the EIGRP neighbors are established I don't have to add the static route, however I'm still not able to get the Spoke router to communicate to communicate with my inside LAN throught the Hub router. I was told I don't need to add a static route. Still curious why it doesn't work.

bkepford

It looks like you need to add
access-list 101 deny 192.168.0.0 0.0.0.255 192.168.0.0 0.0.255.255
to your hub router it looks like traffic is being NATed that should be pushed down the tunnel. You have that entry on your spoke so it probably works

bkepford

nevermind saw this
access-list 101 deny ip any 192.168.0.0 0.0.255.255
I was staring at the screen so long I guess I went a little cross eyed

bkepford

You have an access list 102 on your internal interface do a "debug ip packet 102" and then try and see if the access-list is denying return traffic

bkepford

nevermind it is an inside rule that has a permit ip 192.168.0.0 0.0.255.255 any which should allow all traffic going out.
You say your tunnel is coming up from router to router but LAN to LAN you have a problem?

I found the issue, I have a ASA5510 that is behind the 2821 router which filters all internet and VPN traffic. I had to added and modify the following:

router eigrp 255
redistribute ospf 100 metric 1000 100 255 1 1500
passive-interface GigabitEthernet0/1
network 192.168.1.0
network 192.168.0.0 0.0.1.255
network 192.168.255.0
network 192.168.0.0 0.0.255.255
no auto-summary

router ospf 100
log-adjacency-changes
network 192.168.192.0 0.0.0.255 area 0

This resolves 95% of the problem. The other 10% now my email server is seems slow. For some reason I can't ping from the spoke router to my email server which is behind ASA5510.

chunjo

ASKER

However, the other 5% (typo) maybe minor issues. I'm able to ping 192.168.1.3 from the spoke's LAN to ASA5510 LAN but not able to ping from the spoke router to 192.168.1.3. Any ideas?

bkepford

You have specify an interface it is probably using the internet interface of the router try
ping 192.168.1.3 /source Ethernet0

chunjo

ASKER

Thanks that worked, I am able to ping from my spoke sites to 192.168.1.3.
I had to change routing table on the PCs and Servers on my LAN to talk to the spoke sites.

After the implemenation, I now have all my LAN devices access ISP1 for internet and ISP2 for VPN. This is still a problem for me because before the implementation I was sharing 2 gateways to access the internet (connections to ISP1 and ISP2), now I'm only able to connect to ISP1 for internet. With the new setup I'm not able to change the modify gateways because all of the devices have a 192.168.1.5 as their gateway. I know I can't load balance on the ASA. Any suggestions please advise.

bkepford

What kind of ISPs do you have and what interfaces are they handing you (Ethernet or T1)? What did you have to change for the vpn to work? How were you load balancing before?

chunjo

ASKER

ISP1 is connected to ASA interface fa0/0 which is connected to a T1 connection. ISP2 is connected on the 2821 Router Serial 0/0/0, 0/1/0, 0/2/0 which is multilinked (3) T1.

Before doing the migration, 2821 router was directly connected to my LAN switch and the ASA was also connected to the same LAN switch. They both have their own gateways, thus I was able to physically have PCs and Servers use both gateways which was on a 192.168.0.0 /23.

After the migration, all the devices are behind the ASA and I'm not able to have same network segment on more than 1 interface on the ASA which bring me back to the drawing board. I really need to use some of the ISP2 bandwidth because it's choking the ISP1 connection. Please advise.

Here is the Original Network Topology.

bkepford

Can you attach ISP1 to the 2821? It should have a spare FastEthernet port. I would then policy route on the 2821. That way you still get the protection of your ASA but it sends all traffic to the router and lets the router decide. In that kind of setup you may want to run the ASA in transparent mode instead of routed.
Here is an example of policy routing

ASKER

Unfortunately, I can't set the ASA as transparent mode because it's natting our servers. Is there a way to redirect traffic to the 2821. If I can redirect VPN traffic to ISP2, then why can't I do the same for internet traffic.

Is it possible to forward internet traffic on VPN_TRAFFIC?

CCBQ-FW(config)# int ethernet 0/2
CCBQ-FW(config-if)# ip address 192.168.192.2 255.255.254.0 
CCBQ-FW(config-if)# nameif VPN_TRAFFIC

I'm not sure what IOS load you have on your router but if you can do a VPN you can do NAT on the 2821 as well

chunjo

ASKER

Is there a way to perform NAT on the ASA to that will route 192.168.0.0 /23 to 192.168.192.1 (2821 Router). The ASA has a persistant route statement that points all traffic to 69.38.228.97 which is the outside interface of the ASA.

route outside 0.0.0.0 0.0.0.0 69.38.228.97 1

would it be possible to add another route statement:

route outside 192.168.0.0 0.0.255.255 64.115.1135.170 1

I was told this wasn't possible. Is there any other way of performing this?

I had to to perform following to resolve the issue:

1. Router is in front of the ASA.
2. Configure OSPF on the router and ASA.
3. redistribution EIGRP to OSPF on the router and configure OSPF.
