ASA 5510 L2L tunnel problem

Hi,

We have ASA 5510 with ISR router. ISR router is having 2 internet link from same service provider and 2 pool of ip address for 2 intenet link. One is 512 and another is 2MB link. VPN traffic is going via 2MB link aand Internet Link is having 512Kbps. VPN configuration is done at ASA 5510. Tunnel will get establish and if i try to copy around 600MB file from the remote lan through windows file share it will copy arond 200MB and after that it will get disconnect and it will give error no network path no longer available but tunnel will be up.

Please help us to resolve the issue.

Thanks,

Ram

Hi Ram

Can you try to block the traffic in your router which is using port 445 ?

You can do the same using ACLs for more info you can refer this link.

But do make sure that you arent running any application on the particular port...
