Please help with my access list

[daidem77]

I have made IPSec connection with my branch office succesfully but we can't ping each others inside ip address. Yesterday I was able to ping the IP address of the branch office inside private ips. But today after some changes I have lost that too. Please help me, I am going crazy here. This is my configuration.

Head Office Peer
ip address outside xx.xx.xx.xx 255.255.255.248
ip address inside 172.20.0.1 255.255.0.0

Branch Office Peer
ip address outside dd.dd.dd.dd 255.255.255.0
ip address inside 172.22.0.1 255.255.0.0

After reading I made the change to the following line but still the same problem

nat (inside) 0 access-list outside_cryptomap_30

 

[daidem77]

I am desperate to get this access list working. Can anyone please help me. I have made a ipsec conneciton but unable to ping the private network on both sides.

Try debugging ICMP as a first step. Also, what's the branch office config look like?

 

[daidem77]

The problem here is that the branch office router is a Linksys - WRV54G (#$@#$@#$@#$#@#!#$- that is how much I love the piece of %&^%*&%) and I can't get a command line configuration. Anyhow I am able to get a ipsec connection. IKE phases goes throw and shows connected. I was also able to ping once to the internal network of the branch office lan (172,21.0.0)but not vice versa.

ICMP Trace shows the following when I ping from the PIX.

ICMP echo request (len 32 id 9233 seq 0) xx.xx.xx.xx > 172.21.0.1
172.21.0.1 NO response received -- 1000ms

Thank you for taking the time and any type of advice or help is appreciated.
