inbound TCP connection denied flags SYN on interface inside

Hi people, here again ,

I am having a problem with the traffic from the inside network to outside network, traffic is being dropped I don't know why or how to fix it. My set up is a s follow:

in the outside network there is a router directly connected to the ASA (through the outside network 10.15.1.x), this router creates a different network that is 172.16.35.x.

I'd need to access from the internal network to the network 172.16.35.x. I can't, packets are dropped with the message:

%ASA-2-106001: Inbound TCP connection denied from IP_address/port to 
IP_address/port flags tcp_flags on interface interface_name


I created an access rule to permit ip traffic from inside to network 172.16.35.x, which is connected to the outside interface through the router
Still not working....

Thanks in advance,

Juan
