PC Anywhere on PTPP connection

Hello everybody,
i’m trying to access our corporate network from outside for remote control.
I have setup a PTPP connection which is working fine, using a different subnet from internal network because proxy ARP is creating a mess in the network.
I can ping machine but when i try to access any machine with PC Anywhere i don’t get any result. I have also tried to telnet on machines where pcanywhere is waiting for a connection , on port 5631 and/or 5632 with no success, but this is working within the same subnet.
What am i doing wrong and/or missing?

thanks in advance for your help

Make sure that your forwarding filters are allowing the traffic. Possibly you are allowing ping but blocking other traffic.

Thank you for your suggestion.
Here is my filter rule’s list;

/ip firewall filter> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=input action=accept protocol=icmp

1 chain=input action=accept connection-state=established connection-type=“”

2 chain=forward action=accept connection-state=established

3 chain=input action=accept connection-state=related

4 chain=forward action=accept connection-state=related

5 ;;; Winbox
chain=input action=accept protocol=tcp dst-port=8291

6 ;;; Telnet
chain=input action=accept protocol=tcp src-address=192.168.1.0/24 in-interface=ether1 dst-port=23

7 chain=output action=accept protocol=udp dst-port=123

8 chain=input action=drop connection-state=invalid protocol=tcp

9 chain=forward action=drop connection-state=invalid

Could you give me an idea of what’s wrong or missing?

Thank you in advance
