Good Morning,
i have a question for the community :)
My configuration:
Modem router Telecom for WAN connection (192.168.1.1)
Cisco RV110 (192.168.1.100) for manage 2 local LAN with different class (192.168.2.x and 192.168.5.x) that can not communicate each other.
The request is NAT a port for an Ip address on VLan (2.x)
I had configured the Telecom Router with this rule (TCP EXT 82 -> TCP INT 82 to IP 192.168.1.100 "cisco"), after i created a rule on Cisco (TCP EXT 82 -> INT 80 to 192.168.2.10).
The packet arrive with destination (i checked with wireshirk) but on different port for example:
91.252.189.137 192.168.2.105 TCP 74 [TCP Retransmission] 22080→84 [SYN] Seq=0 Win=14000 Len=0 MSS=1380 SACK_PERM=1 TSval=1259661 TSecr=0 WS=32
Why the port are different.
