connecting switch 3550 to firewall
Posted on 2003-10-29
I have 2 network connecting to centreal switch 3550
first network has switch (2950) at ip 18.104.22.168 mask 255.255.255.0 gateway 22.214.171.124
secound network switch (2950) at ip 126.96.36.199 mask 255.255.255.0 gateway 160.16..211.1
they are both connect to central switch 3550 ip 188.8.131.52 mask 255.255.255.0
switch is set to ip routing
port 1 of 3550 ip set to 184.108.40.206 (wich connect to network1)
port 2 of 3550 ip set to 220.127.116.11 (wich connect to network2)
Now I want to connect pix firewall 515 to 3550 to protect from a 3 network comming into outside interface of firewall.
(pix inside interface ip of 18.104.22.168 mask 255.255.255.0)
(pix ouside interface ip of 22.214.171.124 mask 255.255.255.192) (uncertain of this ...this is what was given to me)
I am uncertain of what gateway to give to central 3550 switch
in order to direct traffic wich is not destin for 160.16.209. and 160.16.211 to go to firewall
I guess i want to know if i should give gateway of central switch 3550 to ip of firewall and give gateway of inside interface of firewall to ip of central switch
Or do I creat a port on central switch for example port 3 give it an ip of 126.96.36.199 and connect the firewall to it. give central switch gateway of 188.8.131.52 and also give gateway of firewall inside to 184.108.40.206
Or am I completly lost??
Should I be looking at creating VLAN instead? pros and cons to Vlan?
