having as very strange issue with the above routerboard. IOS 5.12/2.38
port 1 - ip 192.168.1.254/24
port 2-5 switched - port 2 has IP 172.16.32.1/24
I can ping all hosts from network 172.16.32.0/24 to 192.168.1.0/24
I can ping all hosts from network 192.168.1.0/24 to 172.16.32.0/24
I can initiate any TCP connection from network 192.168.1.0/24 to 172.16.32.0/24 hosts
BUT I can NOT initiate any TCP connection from network 172.16.32.0/24 to 192.168.1.0 hosts. I as soon as a connection from host in network 192.168.1.0/24 to a host in network 172.16.32.0 has been established, I can establish new TCP connection from host in 172.16.32.0/24 net to host in 192.168.1.0/24 network which has initially established a connection.
It looks like a ARP issue, though looking at the MT router the ARP entries of the hosts I try to reach are there. Again, ICMP is working both sites.
The MT is default setup, therefore no other filters/rules etc installed, except as specified, ip address and routes
I am very on the edge to throw something therefore, appreciate any help! The issue is that the MTh is in production, I am in the Pacific all all other MT's with GB interface are also in production and can not be removed.
I am wondering if somebody can verify if this is an issue with the particular board/IOS.
