I am trying to get two inside interfaces on a pix 515E running 6.3 to talk to one another. I have attached a picture of what I am tring to do. One interace has a security level of 100 the other has a security level of 98.. I cant for the life of me get the 98 level interface to talk to the 100 level interface...
Thats correct. You should permit traffic specifically.
for example you want your vlan3 clients to reach internet (www), then add
access-list inside_pc_vlan3_access_in permit tcp 192.168.6.0 255.255.254.0 any eq www
access-list inside_pc_vlan3_access_in permit tcp 192.168.6.0 255.255.254.0 any eq dns
For best practise, I strongly recommend you to apply ACLs traffic specific instead any any, so remove access-list 101 permit any any.
access-list vlan3_access_in permit 192.168.6.0 255.255.252.0 192.168.5.0 255.255.255.0
access-group vlan3_access_in in interface vlan3
static (nativevlan,vlan3) 192.168.5.0 192.168.5.0 netmask 255.255.255.0
Please post your config for me to determine correct interface names, if above doesnt work.
