Site-to-Site with C1841's and multiple Subnets

david.morrow · ‎02-19-2008

Hi all. I have a pair of Cisco 1841's running a site-to-site VPN between siteA and siteB with 192.168.30.0/255.255.255.0 and 192.168.16.0/255.255.252.0 respectively. All works fine between these two subnets.

I am trying to add an additional subnet at siteB, so using SDM, I added the subnet to the IPSec rules on each of the 1841's.....but siteA cannot see the devices on the new subnet at siteB and the device is routing the packets to the internet.

Any help would be greatly appreciated.

Why not use the CLI to accomplish this? Both Cisco IOS SDM and

ASA ASDM are not reliable anyway

siteA:

Before:

access-list 101 permit ip 192.168.16.0 0.0.3.255 192.168.30.0 0.0.0.255

After:

access-list 101 permit ip 192.168.16.0 0.0.3.255 192.168.30.0 0.0.0.255

access-list 101 permit ip 192.168.16.0 0.0.3.255 new_net_on_site_B

-----

SiteB:

Before:

access-list 101 permit ip 192.168.30.0 0.0.0.255 192.168.16.0 0.0.3.255

After:

access-list 101 permit ip 192.168.30.0 0.0.0.255 192.168.16.0 0.0.3.255

access-list 101 permit ip new_net_on_site_B 192.168.16.0 0.0.3.255

Before David posted the question in this forum he also posted the same question in the General forum where it has received a response also. I suggest that any further discussion be consolidated in the original forum.
