Need help for port forwarding

By chinesehkl ·
Hello guys,
Please anyone could help me? I want to send packets from HostA to HostB at port 1234, but my ISP is blocking all non-standard ports. I have below idea but I don't know if it really can work or not.
1. At RouterA, configure outbound port forwarding to replace destination port to a standard port, for example TCP 110 and send over the packet.
2. At RouterB, configure inbound port forwarding to replace destination port from TCP 110 to TCP 1234.

HostA -----< RouterA >----------( ISP )----------< RouterB >-----HostB

Do you think this setup can work?
If yes, anyone can recommend which router I should use? (reasonable price and reliable)
If no, any other solution to send over the packet bypassing my ISP firewall? VPN?
Appreciate for your input.

There are TR members who specifically seek out problems in need of a solution. Although there is some overlap between the forums, you'll find more of those members in 'Q&A' than in 'Discussions' or 'Water Cooler'.
