Hi,
i have a cisco ASA 5510 and need to be able to have 2 subnet communicate with each other.
Ethernet 0/0 is the outside connection
Ethernet 0/1 in the main inside connection 192.168.32.x
Ethernet 0/2 is the 2nd inside connection 192.168.33.x
Both int 1 and 2 can connect to the internet but they cannot communicate with each other.
Please help?!?!
Thanks
Christian

Dear Chris,
Please try to add these steps to you ASA :-
- change the security level of inside2 interface to 50 instead of 100.
- Add these ACL
access-list internal extended permit ip any any
access-list internal extended permit icmp any any
access-list external extended permit icmp any any
access-list external extended permit ip any any
access-list internal1 extended permit ip any any
access-list internal1 extended permit icmp any any
access-group external in interface inside
access-group internal1 in interface DMZ
access-group internal in interface outside
access-group external in interface inside
access-group internal1 in interface DMZ
access-group internal in interface outside
Also change the static NAT to (static (inside,DMZ) 192.168.0.0 192.168.0.0 netmask 255.255.0.0)
Let me know if this work,

Hi Christian,
You have named that DMZ interface as inside1. So please apply like the below and check.
access-group internal1 in interface inside1 and check. It should work.
Please do rate if the given information helps you.

Hi,
Thankyou very much.
The pings are now working one way (from inside to inside 2) but not the other way
DMZ interface wasnt recognised on the line:
access-group internal1 in interface DMZ
cheers

I fiddled about with what you sent me
I adjusted the line to:
static (inside,inside2) 192.168.0.0 192.168.0.0 netmask 255.255.0.0)
From
static (inside,inside2) 192.168.33.0 192.168.32.0 netmask 255.255.255.0
So yes that helped alot thanks
