Red Hat 8 - Policy-based Routing

I have a issue with routing inside the RH8 server.

So the concept is:

1x Red Hat server with 2 interfaces (different VLANs; 150 & 160)

interfaces teamed like:

IP 192.168.50.150 - interface: team0.150
IP 192.168.60.200 - interface: team1.160

1x Windows 2012 R2 server with 1 interface (different VLAN; 180)

IP 182.10.50.180

Windows can ping/ssh/telnet to 192.168.50.150 (vice- versa) and it is routed via network equipment but there is a need to access other IP 192.168.60.200 on the same server from Windows server but it is isolated network and it cannot be done via physical layer..

so I create IP routes as followed:

RED HAT server: 182.10.50.180 via 192.168.50.1 dev team0.150 metric 405

Windows server: 192.168.60.200 255.255.255.0 192.168.50.150

On the Red Hat server:

ip forward is enabled

cat /proc/sys/net/ipv4/ip_forward
1

rp filter is set to loose on all interfaces

sysctl -w "net.ipv4.conf.all.rp_filter=2" net.ipv4.conf.all.rp_filter=2

I cannot just forward all packets from interface team0.150 to team1.160 because other traffic is also coming to both interfaces.

Ping is not working between interfaces team0.150 and team1.160 when I specify interface, otherwise it works somehow.

Firewalls are down localy on the servers and all ports are allowed on physical firewall. What else should I try to make it work?

Thanks!

If you can, please include configuration file as well for further clarity.

@JohnGreene - solution could only work via VPN, because of poor performance it is declined

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
