We have added to our existing network an HP v1910 switch with the purpose of adding two VLANS. The computers in these two VLANS will need internet access, to communicate between the two VLANS and also to be able to contact computers that are still in the current network segment.
I have configured the VLANS on the HP switch and added a test computer in each VLAN. The following is what works and doesn't work. I have also included screenshots of relevant information and a diagram of the physical layout.
Devices in VLAN2(computer A) and VLAN3(computer B) can communicate with each other and access the internet without problems. I had to add the two static routes (as seen in the diagram) on the ASA 5505 to make this work. The problem is that devices on VLAN2 and VLAN3 cannot connect to devices on the original network outside of the HP v1910 switch. (as illustrated by computer C and the DHCP server) My feeling is there is another static route or routes that need to be configured either on the ASA or the HP switch. Advanced network routing is not my expertise but I do understand the basic concepts and can usually manage, but this has had me confused for days. Also, I'm not sure if I have the ports tagged right since I don't have a good understanding of that purpose so I just left everything as default untagged. Any help would be appreciated as I have scoured the internet for help to no avail. I'll try to attach images below if I can figure out how.
