Frequents disconnection when connecting to serveurs behind ASA 5520

[roussillon]

Hi all,

Since several weeks ago we are triyng to solve a disconnection problem related to servers benind an ASA 5520

behind this ASA there are:

-subnet  with public ip addres

-sunbet with prive ip address, the server on this subnet are acccesible via NAT.

the problem is worst when some ousite our  network and behind a nat device (like a adsl modem/router) tries to connect to those servers wich are using natted ip   behind the ASA.

I tried from my home to connect to this ASA5520 using annyconnect  and get reset tcp packets. Are there some aditional configuration to make the ASA work properly?. We have other firewalls like PIX or software firewall (ASG), they work with no problem. Only the ASA 5520 has this issue.

Any help please?

Hello Roussillion,

Would you mind to post the running-configuration and the source IP address and the destination IP address so we can take a deeper look into this proble.

I will be waiting for the reply

Thanks,
