problem with asa 5505 routing,nating

mafija1975 · ‎02-14-2012

i have the asa 5505 with asdm 6.4(5). my inside lan is 192.168.0.0/24. the outside of asa is connected on lan 10.13.74.0/24 and i need over lan 10.13.74.0/24 connect on lan 10.15.100.0/24. i puted nat rule on asa 5505 and acl rule and users from lan 10.15.100.0/24 can connect on my server, but i can't connect on from inside of asa connecet on lan 10.15.100.0/24 and 10.13.74.0/24. my configuration asa is

Result of the command: "show running-config"

Hello,

I reviewed the configuration that you attached, and noticed that you have a static translation for one server and the Port Address Translation (PAT) for the internal host. In some cases, the NAT rules with "any,any" keywords can cause some issues with the proxy ARP feature on the ASA.

I would like to suggest you to change the following NAT rule in order to use the following:

Instead of:

object network server

nat (any,any) static 10.13.74.34

Use:

object network server

nat (inside,outside) static 10.13.74.34

Use the following command to enable ICMP inspection:

fixup protocol icmp

Also, please noticed that if you are not able to ping the ASA, you should check the ARP entries of the device that is doing the routing for 10.15.100.0/24 (it seems to be that 10.13.74.1 is the default gateway of the ASA, not sure if that is the routing device that provides connectivity to 10.15.100.0/24). If such device has an ARP entry for 10.13.74.33, it should be associated with the MAC address of the outside interface of the ASA.

Another test would be to try to ping from the ASA to an IP address that belongs to 10.15.100.0/24.

After you hace changed the NAT rules, please attach the show nat detail to this post so I can check if.

Let me know the results.

Thanks.

my network configuration is: the asa 5505 connect LAN inside of asa 5505 (192.168.0.0/24) and WAN side of asa 5505 (10.13.74.0/24). the router is on 10.13.74.1. i want connect my LAN 192.168.0.0 with network 10.15.100.0. The administrator on router 10.13.74.1 is made the routes which connect two network 10.15.100.0 and 10.13.74.0. when i try ping network 10.15.100.0 from asa i can't do it. I also can't ping from my local LAN 192.168.0.0 outside interface, i can't also ping hosts on network 10.13.74.0(WAN side asa 5505). Hosts from Network 10.15.100.0 can ping NAT address of my server 10.13.74.34 and outside interface of my asa 5505.

what i do?

thanks
