FWSM Queries

[adamgibs7]

Hello Experts,

I have 2 question for FWSM, and i hope i will get answers from you'll

• i created interface vlan 100 on FWSM and enable telnet for that interface i was not able to telnet, but when i created another interface interface vlan 200 then only i was able to telnet. I tried again to confirm , i removed the interface vlan 200 and tried to telnet i was not able to telnet, but again why i created a vlan 200 i was able to telnet. WHY ???????????
  

int vlan 100

nameif inside

security-level 100

int vlan200

nameif outside

security-level 0

• I was not able to upload IOS with TFTP until and unless i enabled a icmp permit any inside command, though i created a access-list permit any any inside and i applied with access-group to inside interface but zero results , BUT when i applied icmp permit any inside all started working fine,WHY ????????????
  

Thanks
