Hi all
I have small industrial segment of network 10.0.0.0/24 (unchangeable) with some devices:
- GSM router (it’s not mine, i have no access to its configuration) 10.0.0.1
- device 1 (unchangeable configuration) 10.0.0.2 gw 10.0.0.1 service TCP:502
- device 2 (unchangeable configuration) 10.0.0.3 gw 10.0.0.1 service TCP:502
- MT CRS112 192.168.0.254/24 (office side) SNAT to 10.0.0.254 (industrial side)
Is there a possibility to access to several services (10.0.0.2:502, 10.0.0.3:502) from office network 192.168.0.254:502|503 without changing devices’ configuration ?
On previous projects I used additional Linux machine on industrial network (eg. raspberry PI) with redir software. (example config RPI IP:10.0.0.253 GW: 10.0.0.254 nohup redir --caddr=10.0.0.2 --caddr=502 --lport=502 --laddr=10.0.0.253 &). On my CRS112 I did only DNAT to raspberry PI and had access to given services from office network.
It worked quite good, but this solution generated additional costs (raspberry PI with housing and adaptor $70) and had average performance.
Is there a possibility to do the same functionality without linux machine & redir ?
I was also thinking about running OpenWRT+redir on metarouter but CRS112 has only 16MB of flash.
