Hi,
I have installed ASA 5510 to limit sessions of Users to 170. But as soon as i put it infront of network before router, Internet goes down and i cannot browse or something.
The network is simple, Cisco three layer model with users on Wired LAN/Wireless LAN using WLC. Approx 2500-3000 users.
Can you please guide me what i am doing wrong in Config or how to start troubleshooting?
Running Config is pasted below.
Thanks in Advance.
Regards,
Bilal

Hello,
The security level on the outside interface is 100 and should be 0.
Also, I dont see nat configured but maybe it is not needed.
Regards,
Felipe.

Hi,
Normally, interfaces on the same security level cannot communicate. So please change your outside leg security level to 0 and try to access internet or you can below feature of ASA with same security level.
same-security-traffic:
To permit communication between interfaces with equal security levels, or to allow traffic to enter and exit the same interface, use the same-security-traffic command in global configuration mode. To disable the same-security traffic, use the no form of this command.
Syntax:
same-security-traffic permit {inter-interface | intra-interface}
no same-security-traffic permit {inter-interface | intra-interface}
Note:
This command is disabled by default.
show running-config same-security-traffic - Displays the same-security-traffic configuration.

Hi,
Thanks for guidance. Now its working good.
One more question, i have limited all users to max 170 sessions/client plus 100 embroynic connections. And its dropping sessions above that. How can i find that which sessions are dropped for any particular user or as whole?
Also Peer-to-Peer(torrents) are consuming lot of sessions. As soon as any user open P2P, his http and other tcp connections dropped. how to check that dropped connections?
And how to block these torrent ports?
Please guide.

Bilal

Hi,
Is there any way we can put cap on per user anywhere in router, firwall or WLC?
Becuase from shared pipe, when one user sucks the bandwidth others have to say suffer.
Please guide where should i limit that per user.
Thanks
